to the right june 2005 section B first question if the first link does not work
- Relevant Equations
- First harmonic equation?
A couple of questions on this. How would the sound get reflected back from the surface of the water? And therefore create a stationary wave would the sound not travel though the water at a faster speed then reflect back and intefere? Or does a small amount of the sound reflect back? Part B mentions a frequency and two different lengths, so could it be possible to get the same frequency at two different haromics?
