Question

A rope is vibrating so as to form the standing wave pattern shown. What harmonic is shown in the pattern?a- eighthb- fourthc- fifthd- thirde- 10

Answer 1

Given:

A standing wave of a vibrating rope

To find:

Harmonic shown by the standing wave pattern

Step-by-step explanation:

The given standing wave pattern of a vibrating rope shows a fourth harmonic as the wavelength of the standing wave is half of the length AB of the material.

The wavelength, in this case, is given as:

`\lambda_4=(1)/(2)L`

Final answer:

The given wave pattern of a standing wave of rope shows a fourth harmonic.

Thus, the correct option is (b) fourth
