Question

What type of reflection of light takes place from:
(a) a rough surface?
(b) a smooth surface?

Answer 1

Answer:

(b)For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection.

(a)For a rough surface, reflected light rays scatter in all directions. This is called diffuse reflection.

Answer 2

(a) Diffused reflection

(b) Specular reflection

Explanation:

Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection. For a rough surface, reflected light rays scatter in all directions. This is called diffused reflection.
