Which represents Wave on the String. The simulation allows changing the amplitude, frequency, set up the string with fixed end, loose end and no end. You may adjust the frequency of the source and whether the ends of the medium are fixed or free. For some frequencies, you will not be able to establish a standing wave. The simulator builds up the standing waves slowly, so be patient before deciding whether a standing wave has been established, see what happens.
Part A: Fixed at both ends
1. Find the lowest frequency that will establish a standing wave. This is the fundamental frequency.
