Chapter 14, Problem 97A

To determine

To Sketch: the result of four cases of wave given below.

Explanation of Solution

Introduction:

A pulse wave is a non-sinusoidal waveform. It has one major crest which usually arises due to sudden disturbance.

The resulting wave for each case when two wave pulses overlap is shown below:

  

When the crest meets a trough, the amplitude of resultant wave is small while when crest meets crest, the amplitude of resultant wave is large.
