Answer: Diffuse reflection
Explanation:
Diffuse reflection is a reflection which can be defined as the reflection of incident rays (light) from the surface where the incident ray on the surface is scattered at many different (places)angle as compared to smooth reflection that place at a single angle.
This takes place where the surface is rough and the light falling on it falls at many different angle of incidence.
Here, the rough paper is also an example of the diffused reflection in which the light diffuses with great efficiency.
