Chapter 12.1, Problem 1R

To determine

To explain: Two ways to direct light waves around a corner.

Answer to Problem 1R

Interaction with objects and internal diffraction are the two ways through that anyone could direct a light wave around corners.

Explanation of Solution

Introduction:

A repeating movement (or disturbance) that transfers energy through space or matter is known as wave.

It is known that light wave bends (always) around corners to some extent. To direct a light wave around corners, use mirrors to change the direction of light and use glass or plastic cups (or any other obvious substances) to refract (or bend) light.

Conclusion:

Mechanisms that cause light wave to bend around a corner are interaction with objects and internal diffraction.
