Chapter 29, Problem 8A

To determine

The way in which the law of reflection holds good for the diffuse reflection.

Explanation of Solution

Introduction:

When the reflection process occurs through rough surfaces such as paper, cloths, and asphalt roadway, this type process is said to be the diffuse reflection.

The light beam is a bundle of the various individual light rays which move parallel to each other and each ray follows the laws of reflection. If the incident surface is rough, then the light rays get reflected and diffuse in various -different directions. The normal lines at the incident’s point are different for different rays in the case of rough surfaces. After the reflection from the rough surface, the reflected rays are scattered in different-different directions.

Conclusion:

So, its can be said that the rays are incident in a concentrated bundle on the incident surface while are diffused upon reflection.
