How do you find the angle of reflection off of a mirror?

already exists.

Would you like to merge this question into it?

already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

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.

Does sunlight reflected off a mirror increase the temperature of the sun-rays?

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 (MORE)

What does a mirror reflect facing a mirror?

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 (MORE)

Why do mirrors reflect?

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 (MORE)

What is the angle of reflection?

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 (MORE)

What is reflect angle?

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!!

At what angle does a light ray reflect off a mirror?

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 (MORE)

What angle does a light ray reflect off a mirror?

the same angle with which it (the incident ray) hits the mirror surface. this physical law is known by the formula α = β. there´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 (MORE)

Do the light rays reflecting off the convex mirror ever cross each other?

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 (MORE)

If light hits a mirror at an angle it reflects back at?

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

How is light reflected off of a concave mirror?

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 (MORE)

How does light reflect off of a mirror and water?

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 (MORE)

How can light reflect off a mirror?

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.

Is light bouncing off a mirror reflected or refracted?

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.

What is reflecting mirrors?

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 an angle reflection?

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 (MORE)

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 (MORE)

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 (MORE)
