1. The problem statement, all variables and given/known data Draw a sketch of of a standing wave created by a string fixed at two ends, the frequency is 60 Hz, the wavelength is 0.4 m. Draw a profile with times t=0, T/4, T/2, 3T/2 2. Relevant equations period= 1/frequency, 3. The attempt at a solution i know that at t/4, you will have a quarter of a wavelength going down the string at 1/240 seconds, but does it get reflected back? or is it just a quarter bump gowing towards the end, and the rest of the string is straight?
