Question

Is law of reflection valid for diffuse reflection. Justify your answer​

Answer 1

Yes , in curved surface we have to draw tangent to make law of reflection valid.

Answer 2

Reflection is the phenomenon of bouncing of light in the same angle as the of incidence .

Diffuse Reflection is a special phenomenon.

Diffuse reflection turns one ray of light into multiple rays of light, pointed all directions. The law of reflection says that one ray of light is reflected into one ray of light. Further, the angle of reflection has to equal to the angle of incidence. ... (“Specular reflection” - speculum being latin for “mirror”.)
