1. Homework Statement
Drive one end of the string with sinusoidal oscillator of frequency 100hz. What velocity is required to setup a standing wave with 5 segments?


2. Homework Equations
I know for standing wave that fn = nV/2L and you can isolate out velocity variable.


3. The Attempt at a Solution

Though I'm not very familiar if the string is not tied down at both ends and I was wondering if someone could explain how to obtain the velocity from the 2 givens.

You don't have enough information. You also need the total length of the string.

The standing wave in a string fixed at one end and free at the other end will look the same as in a pipe closed at one end and open at the other end.
