How do you find the angle of reflection off of a mirror?
The angle of reflection (θr) off a planar surface (eg. mirror) is equal to the angle of incidence (θi) on that surface. They are measured with respect to the normal, which is an imaginary line drawn perpendicular to the surface.
Or, in simpler terms, the angle of reflection is the same as the angle of incidence.

It depends \n. \nA standard planar mirror will not increase the energy contained in the rays that reflect off it. In fact, there will be some loss of energy since the reflective surface is not perfect. There is some reduction in the light's intensity as it passes through the mirror's glass and re…flects off the backing surface.\n. \nParabolic mirrors, on the other hand, focus and concentrate the light rays on a single point in front of the mirror, aptly named the focus . Although the energy is not amplified, it will be effectively increased because of the additive effect that will result when the light energy is concentrated.\n. \nTo clarify, the "rays" of the sun, i.e. the photons (energy), do not have any temperature at all, they interact with matter and heat the matter up.

Answer . Light travels at about 186,000 miles/second... If the mirror is 3 ft away, the light has to travel 6 ft... you do the math.
A "mirror" is defined as something that reflects visible light. Therefore, two mirrors facing each other will only reflect any light that comes into contact with them, along with any visible distortions inherent to the reflecting process, such as coloration from the metal in the mirror and impuritie…s in the glass. Given two theoretically "perfect" mirrors facing each other, the only thing reflected would be light. In the absence of friction or other interference, the light would travel infinitely and eternally. If one were able to look directly at this, one would literally just see light, as far as the eye could see. Contrary to popular belief, mirrors do not reflect images. They reflect the light coming from objects and redirect that light to the human eye, giving the impression of an "image." In reality, the eye is seeing the actual object. It's just that the light coming from the object has been redirected. (MORE)
Mirrors Because if they didn't, they wouldn't be mirrors; they'd be windows -- or walls! Perhaps you wish to know how they reflect or why some surfaces reflect whereas others don't. There are basically three types of surfaces: those that absorb light, those that reflect it, and those that neithe…r reflect it nor absorb it. Not counting "black holes," there are no objects that absorb all light perfectly or reflect all light perfectly or pass light perfectly. All objects reflect and absorb light to some degree. Some reflect more than absorb, some absorb more than reflect, and some -- like windows -- let light pass right through them. Mirrors are highly reflective, whereas black cotton or wool fabric doesn't reflect much at all. So, let's take a look at stuff that reflects. A mirror reflects, but so does a piece of loose-leaf paper. If the paper did not reflect some light, it would be invisible to the human eye. If it absorbed all the light that struck it, there would be nothing for your eye to see, because when you "see" the paper, you are actually detecting the light reflected from it. But a piece of paper is not a mirror, is it? So, what's the difference? The difference is the amount of "scatter" or diffusion caused by the surface of the paper. When the light rays hit the surface of the paper, they don't bounce off in the same direction; they scatter in many directions. We characterize that phenomenon as diffuse reflection. This occurs because the surface of the paper, when viewed under a microscope, is uneven, granular, and bumpy. See the nearby link for a diagram of light rays hitting a surface and scattering. The rays are bouncing off in all different directions. Objects that produce diffuse reflections don't make very good mirrors. But when light rays hit a very flat, smooth, polished surface, they bounce off at very predictable and consistent angles. They don't bounce off in all directions. In fact, the measure of the angle at which the light hits the surface (the angle of incidence) is the measure of the angle at which the light bounces off the surface (the angle of reflection). When this happens, you have a mirror. See the nearby link for a diagram depicting reflection. the back of a mirror is a thin layer of metal. well polished metal reflects images. Mirrors show reflection by light will reflect at a mirror surface so that the angles of incidence and reflection are equal. Mirror has at least one reflective object so that shows the image, that you put in front of that mirror. And how they work is that light helps you see your reflection in a mirror ; Light is energy traveling at high speed. And when it hits ah object all the energy has to go somewhere. - Melissa Lindsay (: The back part of the mirror is made of of metal. They polish the metal. Because metal reflects light if shows your reflection. (MORE)
the angle of reflection is the angle where lightbounces off the object. for example if you have a mirror the angleof reflection is the one that you can point a laser at the mirrorand bounces off.
What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 30-degrees with the mirror surface?
This problem can be answered one of two ways.. The easy answer is 150 degree. The other answer is to create a 360 degree model in you head or on a digram of the equation. When an angle is entered onto a surface that is flat it is only half of the circle or 180 degrees. Then because it enters at th…e 30 degree angle its trajectery on its way out is then again 180 degrees minus the 30 of entry leaving the same 150 degrees. (MORE)
A ray of light is incident towards a plane mirror at an angle of 30-degrees with the mirror surfaceWhat will be the angle of reflection?
The angle of reflection is equal to the angle of incidence. It will be at 30 o to the surface of the mirror (from the opposite edge) ^ This answer is not correct for SURFACE, but is correct for RELATIVE ^
An angle of reflection is the angle between the perpendicular and a ray reflected at a surface.
A beam of light strikes a mirror at an angle of 30 degrees with the mirror the reflected light beam will leave at an angle of?
If the angle is measured in relation to normal to the surface of mirror, the leaving ray will be also at angle of 30 degrees, but in opposite direction.
a reflects angle is an angle that is bigger than 180 degrees but less than 360 degrees..i had trouble on this one too..:P hope this helped!!
It reflects at like 45 degrees I think.. No, it reflects off at the same angle it hits the mirror. If the light wave hits the mirror at a 30 o angle on the left side, it will reflect off at a 30 o angle on the right side.. Scientists usually measure these angles from an imaginary line perpendicu…lar to the mirror at the point where the light wave hits the reflecting surface; sounds awkward, but it makes the math easier.

the same angle with which it (the incident ray) hits the mirror surface. this physical law is known by the formula Î± = Î². thereÂ´s a simple way to prove it: look into a (palin) mirror and ask someone else to look into the same mirror - preferrably from another distance. as long as you …can see their reflection they should be able yo see yours and vice versa. (MORE)
The classical physics answer is No . Parallel light rays, normal to the mirror's curve, will not reflect across each other. More Information: Applying Huygens-Fresnel Principle (HFP) and Huygens construction all light signals will cross each other (light 'rays' is a simplistic misnomer) as th…e schrodinger 'sphere' surface expands from each point (via atomic scattering). But using the Ewald-Oseen Extinction Theorem (of destructively interfering waves), the only vectors observed (on the time averaged poynting vector, normal (perpendicular) to the wavefront), will not cross. (MORE)
A beam of light is incident on a plane mirror at an angle of 32 degrees relative to the normal what is the angle between the reflected rays and the surface of the mirror?
Angle of reflection equals angle of incidence, so the light is reflected at 32 degrees relative to the normal. Since the normal is perpendicular to the surface of the miirror, the angle between the reflected rays and the mirror is 90 degrees minus 32 degrees, or 58 degrees.
No at the same angle due to the law of reflection which says, angle of incidence is equal to angle of reflection for even surfaces.
If light hits a mirror at an angle it reflects back at you but it will make the image look bigger or smaller (if the mirror is concave or convex). If it is a flat plane mirror the image is the same but if your holding something it will be on the opposite side
What is the angle of reflection of a light ray that hits a mirror at a 48-degree angle from the normal line?
96 degress? If the light ray is straight, and if the mirror isn't bent, then the angle of reflection is exactly 48 degrees, the same number of degrees as the angle of incidence. That's the law of reflection.
amsw2. A mirror, provided it is smooth to below the wavelength of light, will reflect the light in the same way you can see a water wave be reflected from a wall.
The reflection angle will also be 20 degrees from the normal on the other side of the normal in the same plane.
The angle between the incident ray and the mirror is equal to the angle between the reflected ray and the mirror.
Of course. Any source of light can be reflected from a mirror.. The lightning itself will not reflect from a mirror.
Does the angle of incidence equal the angle of reflection when a straight light ray hits a straight mirror?
Yes, the angle of incidence always equals the angle of reflection when a straight ray of light hits a mirror that isn't bent.
What is the advantage of measuring the angle of reflection and angle incident on either side of the normal to the surface of the mirror?
We measure them on the either side of the mirror and not on the side of the normal to the surface of the mirror because, if the mirror or any reflecting surface is bent, then there will be a difference between the angle of incidence and angle reflection which can be avoided by measuring those angles… on the either side of the mirror. (MORE)
The way light is reflected is different in a concave mirror depending on the position and distance from the object. when light hits the concave mirror when it is near the object, the rays are scattered and it forms a virtual image, i.e it does not come on the screen. the image will be erect and higl…y magnified. When it is taken further from the object, the image becomes inverted and real, i.e it can be seen on a screen, and will still be magnified. (MORE)
when light hits an object some light is absorbed and some is reflected. when it hits a mirror, almost all of that light is reflected. when it hits a white wall a lot of the light is reflected but not enough to form an image our i can detect. a wall is also not smooth so the light is reflected at bil…lions of different angles (MORE)
when you are up close to the mirror you can see more of you than when you back away from the mirror. the reflection changes as you move away from the mirror
What is the angle of incidence if a reflected wave bounces off a mirror with an angle of reflection equal to 55º?
If a light ray is reflected from a flat mirror with a reflection angle of 55 o then the angle of incidence was also 55 o . When reflecting from a mirrored surface, the angle of incidence equals the angle of reflection.
the light bounces of the water and makes the water shine This (above) doesn't really answer the question. It has to do with the light rays going from one media to a different media (air/water). For a detailed description look at this page in wikipedia. http://en.wikipedia.org/wiki/Reflection…_%28physics%29 (MORE)
If several light rays enter a concave parabolic mirror parallel to each other and to the axis of the mirror, then they'll all converge at the focus of the mirror. If they enter the mirror from a variety of directions, then there's no telling whether they might intersect, or where.
Is the incoming beam of light that strikes a mirror at an angle and reflects the same as that of the incoming beam?
Yes, the beam just reflects off of the mirror. There is no beam created from the mirror.
This is essentially correct. A beam of light, when striking the plane of a mirror, will be reflected from that surface at the same angle as the incident beam.
By 'Atomic Scattering', which is the absorption and re-emission of light energy by the particles of a medium which will not absorb the energy. It depends if the mirror is concave or convex. The light reflects differently depending on the type of mirror.
Light bouncing off a mirror is reflected. Reflection is when the light bounces off a shiny surface back to your eye while refraction is when the light changes direction when passing from one medium to another medium of different optical density.
When a light ray is reflected by a mirror is the angle of the light ray and the reflected ray different or the same?
Angle of Incidence = Angle of Reflection This is only true if the angle of incidence is greater than the critical angle.
The angle of the reflected ray with the normal line to the surface of the mirror is the same as the angle of incidence. Snell's law.
-- I could say that it's equal to 90 degrees. I would always be wrong. -- I could say that it's equal to zero. I would usually be wrong, but not always. -- I could say that it's equal to the angle of incidence. At last, I would always be correct.
it depends on how far your looking at it if ur close its small but far its large
When a light ray is incident upon a reflecting surface, the angle of reflection is equal to the angle of incidence. Both of these angles are measured relative to a normal drawn to the surface. The incident ray, the reflected ray, and the normal all lie in the same plane.
What is the difference between a set of parallel rays reflected off a very smooth mirror and the same rays reflected off a more bumpy mirror made of the exact material?
The bumpy mirror will reflect the light at a weird angle, not the one you would expect, based on where the light source is coming from. The smooth mirror will act normal
What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 30 degrees with the mirror surface?
If the ray hits the mirror at an angle of 30 degrees with the mirror surface, the complementary angle that the ray makes with the normal (perpendicular) to the mirror at the point of incidence is (90 - 30) = 60 degrees and since angle of incidence is equal to angle of reflection in a plane mirror, t…he angle of reflection is 60 degrees. (MORE)
What is the angle of incidence if a reflected wave bounces off a mirror at an angle of fifty five degrees?
It makes the same angle, on the other side of the normal, at the point of incidence.
The angle formed by a reflected ray and a perpendicular to the surface at the point of reflection. (Physics / General Physics) the angle that a beam of reflected radiation makes with the normal to a surface at the point of reflection Reflection is the change in direction of a wavefront at an interfa…ce between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves. The law of reflection says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected. Mirrors exhibit specular reflection. In acoustics, reflection causes echoes and is used in sonar. In geology, it is important in the study of seismic waves. Reflection is observed with surface waves in bodies of water. Reflection is observed with many types of electromagnetic wave, besides visible light. Reflection of VHF and higher frequencies is important for radio transmission and for radar. Even hard X-rays and gamma rays can be reflected at shallow angles with special "grazing" mirrors >NMMS< I Love GOD (MORE)
What are value of angle of incidence and angle of reflection for normal incidence of light on mirror?
Both are zero. Thereby it obeys the second law of reflection ie angle of incidence is equal to angle of reflection.
What is the angle of reflection when a beam of light strikes a curved mirror and has an angle of incidence of 40 degrees?
The angle of incidence equals the angle of reflection. Always. If the surface is curved, this is still true. Now for some caveats. 1. If the "beam" has zero width, then there really is no complication. Measure angles relative to the line perpendicular to the surface and in the plane of inci…dence at the point the beam strikes the surface and everything works out perfectly. 2. If the beam has a finite width, then everything still works out, but the beam strikes the surface at more than one point and the reflected beam goes away from the surface at more than one point but at each point, the angle of incidence equals the angle of reflection, but the angle of incidence is different at each point on the curved surface. Still, at each point, one measures from the perpendicular to the surface at that point, just as described above. Some more technical stuff. We may say a beam has zero width if the width of the beam is very much smaller than the radius of curvature of the surface measured at the place where it strikes the surface. Under any circumstances, the beam reflected from a curved surface will spread, i.e. be dispersed at a range of angles relative to the incoming beam and that range depends on the radius of curvature of the reflecting surface. As mentioned above, this is small if the beam is narrow, but if you are observing reflection far enough from the reflecting surface, one can observe the spread. All this assumes "ray optics" where the sizes of the beam diameter and the radius of curvature are large compared to the wavelength of the light. It all gets more complicated otherwise. (MORE)
How does the angle of how the wave hits the surface compare to the angle at which it reflects off the surface?
They are equal. Angle of incidence = Angle of reflection. This is the second law of reflection.
Light will bounce off the surface of a polished mirror in the sameangle of incidence, but the way you see it, it's as if the imageformed behind the mirror surface.
What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 45 degrees with the mirror surface?
The law of reflection: When a ray of light reflects off a mirror,the angle of the incidence ray is equal to the angle of thereflection ray. Therefore, an incidence ray of 45 degrees will have a reflectionray of 45 degrees. As both rays are equal, either side of the normal line, then addingboth angle…s equals 45 + 45 = 90 degrees. The normal line is a lineperpendicular to the surface of the mirror. (MORE)
It can go on forether forth. As long as you have the mirrors, itwill keep going. -Peace is a lie, there is only passion.
What will the angle of reflection when the angle between the incident ray and the reflecting surface of the mirror is 30 degree?
You have given the glancing angle as 30 degree. So the angle of incidence = 90-30 = 60 deg As i = r by the law of reflection the angle of reflection = 60 deg
Those angles are equal at the point where a ray oflight hits the mirror, regardless of the shape of the mirror.
