Chapter 14, Problem 56A

To determine

The difference between a wave pulse and a periodic wave.

Answer to Problem 56A

There is difference of time interval between a pulse and periodic wave.

Explanation of Solution

Introduction:

A periodic wave is the wave that performs repetitions in the same pattern and is used to find the wavelength and the frequency of the wave. Period is the time which is required to complete a single cycle.

A pulse is defined as a wave which is produced by an unexpected disturbance that is caused for a short period of time.

A pulse is defined as a wave which is produced by anunexpected disturbance that is caused for a short period of time.

The medium through which the wave passes oscillates for a short period of time and then returns to the original position.

  

A periodic wave is produced by regular and continuous and regular vibrations of the particles of the medium in which it is passing.

The medium through which the wave passes vibrates for a long period of time after undergoing disturbancein a periodic wave.

  

Conclusion:

Hence,pulse wave and periodic wave differ with respect to the time period involved in their movement.
