1. The problem statement, all variables and given/known data 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. Relevant 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.
