Given information

Given values:

The oscillator's fundamental frequency is  Hz.

The mass per unit length of the string is

The length of the string is .

Step-by-step explanation

Step 1.

The string must vibrate in a standing wave pattern to have a certain number of loops.

The frequency of the standing waves will be the same as the oscillator, which is  Hz.

That frequency is also expressed in

.

The speed of waves on the string is given by

 .

The weight of the masses dangling from the string's end will equal the strain in the string,
