Chapter 9, Problem 15STP

To determine

To describe the formation of a standing wave.

Explanation of Solution

Introduction:

A standing wave is formed when two waves of same frequency superpose in a same medium.

When two wave of same frequency travelling in opposite direction superpose each other in a same medium, formation of a stationary wave take place with nodes and antinodes.

The point on a stationary wave with zero amplitude is called nodes and the point on maximum amplitude is called antinodes.

Conclusion:

Thus, the formation of stationary wave is an interference phenomenon.
