1. Given a string in a standing wave system with a fundamental frequency f1, what would the newfundamental frequency be if you:
a. Pulled the string 4 times harder (Tnew = 4told)?
b. Instead, changed to a 4 times heavier string (µnew = 4µold)?
c. Instead, changed to a 4 times longer length to vibrate on? (Lnew = 4Lold)?
