Question

A beam of light falls on a smooth wall. Will you observe regular reflection or diffuse reflection from the wall?

Answer 1

Answer:

Regular reflection

Explanation:

The wall is smooth so regular reflection will happen.

Answer 2

Answer:

The reflection of light from the walls of our house is irregular, as at the microscopic level, their surfaces are not smooth. This is known as diffuse reflection. The roughness or smoothness of a surface, even if it is microscopical, tremendously affects the subsequent reflection of a beam of light.

It will be diffuse reflection. No matter how smooth the wall looks it is rough on a microscopic scale and will scatter the light.
