Question

Why is the angle of reflection equal to angle of incidence when a light ray gets reflected from a surface?

Answer 1

Because the normal divides angle of incidence and angle of reflection into two equal parts

Answer 2

A very good question.. I once questioned my sir about it and he answered, "because that's what the law states" I was young and was very welcoming so that reason made sense. Now that I think about it..I feel like an idiot... I did some search and here is what I found

If you think that the postulated statement or theory of “ the angle of the light’s reflection is equal to the angle of it's incident” is only monopolized by light alone, please castout such miss consumption straight away now.

What happens to light is happenig to all the bodies irrespective of it's mass and size or weights and volume.

Every moving body travels in parallel and angular movement, where the parallel moment is constant,the angular movement is only opposed by the impact where it carries it's parallel moment unhindered.

Go into a room and try throwing a ball, observe the angle you throw and the angle it bounces off. Now, try throwing it in a wider angle yeah.. notice the difference?? This is what happening to light also.

If you apply the same law in the carom game, you'll win.!
