Answer:

Option (D)

Step-by-step explanation:

Reflection is the phenomenon in which a ray of light strikes on a smooth and polished surface and then bounce back into the same medium at same angle.

There are two types of reflection.

1. Regular reflection or specular reflection

2. Irregular reflection or diffused reflection

When a parallel beam of light falls on a smooth and highly polished surface and after reflection the rays are also parallel to each other, it is called regular reflection.

When after parallel beam of light falls on a rough surface and after reflection the rays of light goes in random directions, it is called diffused reflection.

The rays reflected at 90 degree to - 90 degree in diffused refectory.
