Question

Identify whether the following are due to regular or diffuse reflection.
a) The image of a mountain can be seen clearly in the calm waters
of a lake.
b) Reflection of light from a carpet.

Answer 1

Answer:

Diffuse reflection is the reflection of light from a surface such that an incident ray is reflected at many angles rather than at just one angle as in the case of specular reflection.

The structure of carpet's surface is as shown. Thus it shows large amount of diffuse reflection.
