Question

laws of reflection are valid in regular as well s irregular or diffused reflection. why?

Answer 1

Hi Delsey!

The laws of reflection are:

(1) The angle of incidence is equal to the angle of reflection

(2) The incident ray, the normal, and the reflected ray all lie in the same plane.

These laws are valid irrespective of the surface on which light falls. The irregular surface can be considered to be made up of a large number of small planar reflecting surfaces positioned at slightly different angles. Light falling on these surfaces reflects according to the laws of reflection. It is the surface because of which light-rays diffuse and are not able to form an image

Cheers!!
