1. The problem statement, all variables and given/known data
Consider a string of length L tied down at both ends to fixed points on opposite walls. We are going to pluck the string and make standing waves of a certain fundamental frequency. In order to increase the frequency of the fundamental, which of the following parameters can be varied to accomplish this?
True False use a thinner string
True False increase the length of the string
True False loosen the string
True False use a thicker string
True False tighten the string
True False decrease the length of the string

3. The attempt at a solution
My answers are in bold, not sure what im doing wrong, the computer program doesnt tell me but can anyone help me out?

Thanks
