Question

A standing wave is established on a string that is fixed at both ends.

Answer 1

Answer:

d. The length of the string is equal to one-half of a wavelength.

Explanation:

For a standing waves vibrating with Fundamental Frequency will be vibrate in one loop so  Length 2 L =  λ    ⇒  L = 1/2 λ

Answer 2

Answer:

d)The length of the string is equal to one-half of a wavelength (L = λ/2)

Explanation:

When a standing wave is established on string which is fixed at both ends,

Then the relation between length of the string and wavelength is given by

L = λ/2

In this scenario, the length of the string is equal to one-half of the wavelength.

Another possible case is when on end of the string is fixed and one end of the string is free, in such case, the length of the string is equal to one-quarter of the wavelength.
