Part A. How can you tell whether you have a standing wave? What conditions need to be met to make this work?
Part B. How do you determine wave speed? What happens to the wave speed if you change the frequency or the amplitude?
Part A: The easiest way to identify the standing wave is that the standing wave cannot carry energy and the peak amplitude of the wave doesn't move in space.
Part B: we know V=f*(lamda) so changing frequency results in change in velocity but the the velocity doesn't depend on the Amplitude.
