Question

Define the laws of reflection? Do they obey in case of spherical mirrors?

Answer 1

Hi..

Law of reflection. : a statement in optics: when light falls upon a plane surface it is so reflected that the angle of reflection is equal to the angle of incidence and that the incident ray, reflected ray, and normal ray all lie in the plane of incidence..

Yes. At each point on the mirror, imagine that there is a very small flat piece of mirror that is tangent to the surface there. The light rays bounce off that flat surface with angle of reflection equal to angle of incidence. The next piece over is tilted just a little differently, but with respect to that local tangent, it's still angle of reflection equal to angle of incidence...


Hope this helps u!!
