Answer 2

Answer:

because of the reflection of light

Explanation:

as we know there are two types of reflection regular and irregular

*regular reflection* - When a beam of parallel light rays is incident on a smooth and plane surface, the reflected rays will also be parallel. This type of reflection is called Regular Reflection

*irregular reflection* - Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection.
