Why does the light falling on a mirror obey the laws of reflection?

The virtual image that seems to be behind the mirror is of the same size of the object from where the rays come from. The distance between the object and the mirror is the same distance between the mirror and the virtual image. The most notable difference is that the virtual image is reversed Mirrors have a very smooth surface with very few irregularities - unlike the surface of say paper - which may feel smooth to the touch but in fact is a very irregular surface if seen under a microscope. Light hitting an irregular surface is scattered in all directions so no image can be formed. Light hitting a mirror is reflected in the same order that it strikes the mirror - so an ordered reflection of the object is seen as a clear image. We see objects in a mirror, because a mirror, when hit by particles of light called photons, reflects the photons back to us and some reach, and enter, our eyes. Photons that hit a rough surface will bounce off of the surface in a haphazard manner, while those that hit a smooth surface, such as a mirror, only bounce off of the surface at the same angle at which they hit the object. The scientific term for this phenomenon is reflection. Not all smooth surfaces reflect photons back to us, even though, technically, they should bounce back at the same angle at which they hit the surface. This exception to the rule results, because some smooth surfaces absorb the light particles hitting them, making it impossible for them to bounce back. Another apparent exception to this rule is that, although our bodies are rough, uneven surfaces, off of which light bounces at random angles, our images reflect off of a mirror. The reason for this apparent contradiction is simply that when we stand in front of a mirror, some, but not all, of the light particles bouncing off of us will hit the smooth surface of the mirror. The ones that do reflect our images back to our eyes at exactly the same angle at which they hit the mirror. In other words, photons that bounce off of any part of our bodies and hit the mirror reflect back to our eyes from only one place on the mirror, and at only one angle. It follows that each point on our bodies that reflects back to our eyes from one point on the mirror produces an image in the mirror. All of the images together make up our reflections, like it or not. And remember that mirrors don't lie!

What is the rule for a reflection?

When a light ray hits a surface at an angle (called the angle of incidence) and all or part of it is reflected at an angle (called the angle of reflection), the law of reflection states: the angle of reflection equals the angle of incidence. The angle is measured from an imaginary line drawn perpendicular to the surface at the point the ray hits the surface. what the hecka i dont understand this crap i hate math


Why does the angle of incidence equal the angle of reflection in the case of curved mirrors?

because that's the rule. angle of incident ALWAYS = angle of reflection.


What effects does light have on concave and convex mirrors?

Light has little or no effect on a mirror. The mirrors follow the rule: "the angle of incidence equals the angle of reflection". Concave mirrors concentrate light to a point and convex spread it out.


Why ray of light not bend when it falls perpendicularly on any surfaces?

I think you would have to say that it does ... the portion that's not absorbed is bent exactly 180 degrees from its original path. The result of perpendicular incidence is perfectly consistent with the general rule of reflection that says the angle of reflection is equal to the angle of incidence. In the case where the ray of light falls perpendicularly on the reflecting surface, the angle of incidence ... the angle between the arriving path and the normal ... is zero, and so is the angle of reflection. So what's the problem ?


Why light ray does not bend for normal incidence?

You don't say whether you're talking about reflection or refraction. But either way,a light ray that is incident normal to the surface follows the same simple rule as ifit had been incident at any other angle.-- For reflection, the rule is: Angle of reflection = angle of incidence.At normal incidence, the angle between the incident ray and the normal is zero,so the angle between the reflected ray and the normal is also zero. Notice thatthe ray certainly does bend ... its original direction is bent by 180 degrees.-- For refraction, the rule is (Snell's law): sin(Θ2) = n2/n1 sin(Θ1)At normal incidence, sin(Θ1) = 0 , so sin (Θ2) also works out to zero in the 2nd medium.


What is the rule of reflection?

When light is striking at a mirror the angle it reflects at is at the same angle that the light has been struck at.


In GHK GH equals 19 gk equals 13 and KH equals 22 which angle measures in order from least to greatst.?

The largest angle is opposite the largest side (and so on) - this follows from the Sine rule So GK < GH < KH implies that angle H < angle K < angle G


What is the relationships between the speed of light through a substance and the angle of refraction?

the speed of light is 300,000 kilometers per second to reach ones surfaces ,hence if it completely reacts to a surface it may attempt to reflection,another one is the refraction of light, this one is the opposite of the rule of the reflection' rule


What is the Scientific rule when laser beam hit a mirror and a rule for where it helps you predict where it will bounce off?

The scientific rule for when light returns to the medium from which it originated is called Reflection. The rule for where it helps predict where light will be reflected is called the Law of Reflection.


What is the angle-angle-side rule?

Side-Angle-Side is a rule used in geometry to prove triangles congruent. The rule states that if two sides and the included angle are congruent to two sides and the included angle of a second triangle, the two triangles are congruent. An included angle is an angle created by two sides of a triangle.


How do you solve triangle EFG given that g equals 5 e equals 7 and G equals 43?

It depends on what you mean by "solve". This is the "ambiguous" case so that there are two possible solutions depending on whether F is acute or obtuse. Assuming one or the other, the sine rule will give you angle E and so angle F can be calculated and, from that, side f.
