Select the correct answer.

Light incident on a surface at an angle of 45° undergoes diffused reflection. At what angle will it reflect?

A. only at angles less than 45°
B. only at angles greater than 45°
C. only at 45°
D. at any angle between -90° and 90°
E. only at 0°



Answer :

Diffused reflection occurs when light hits a rough or uneven surface. Unlike specular reflection, where light reflects at a single angle, diffused reflection causes the light to scatter in many different directions.

Here's a detailed explanation:

1. Incident Angle: The light strikes the surface at an angle of 45°.
2. Nature of the Surface: The surface is rough, which causes diffused reflection.
3. Diffused Reflection: When light undergoes diffused reflection, it does not reflect at a single angle. Instead, the rough nature of the surface means that light can scatter in many different directions.

As a result of the irregularities in the surface, the reflected light rays do not follow a single uniform path. They scatter in a range of directions. This means the angle of reflection can vary widely.

Based on the nature of diffused reflection, the correct answer is:

D. at any angle between -90° and 90°
