Chapter 7, Problem 7.1QP

Interpretation Introduction

Interpretation:

The terms wave, wavelength, frequency and amplitude should be explained with a neat diagram.

Concept Introduction:

A wave is a disturbance or variation that travels through a medium transporting energy without transporting matter.

The wavelength is the distance between identical points on successive waves.

The frequency is the number of waves that pass through any particular point in one second.

The amplitude is the vertical distance from the midline of a wave to the top of the peak or the bottom of the trough.

Explanation of Solution

The wave can be in any forms which are shown in the below diagram.

Figure.1

The wavelength is the distance between identical points on successive waves which are shown both in high and low frequency waves.

Figure.2

The frequency is the number of waves that pass through any particular point labelled as $\text{P}$ in one second.  In the diagram, both high and low frequency waves are shown.

Figure.3

The amplitude is the vertical distance from the midline of a wave to the top of the peak or the bottom of the trough which is clearly shown in left side of figure4 diagram.  In the right side diagram, both high and low amplitude waves are shown.

Figure.4

Conclusion

The terms wave, wavelength, frequency and amplitude are explained with a neat diagram.
