Suppose the above two graphs describe a wave, then I've a couple of conceptual questions that I don't fully understand.
1) Is there an analogy that I can use to imagine the graphs?
For GRAPH 1 I generally think about the Simple harmonic motion, A bob oscillating up and down along the y-axis and if we keep on rolling a sheet of paper in the direction of the x-axis we will end up getting GRAPH 1, but what about GRAPH 2?
2) What are the maximum variables that can be inferred from both the graphs? By variables, I mean, quantities such as wavelength, wave velocity, frequency etc.
I know that the amplitude on both the graphs is the same (why?). From GRAPH 1 we can get the frequency, time period and the wavelength, and, therefore, the wave velocity. Does GRAPH 2 allow us to calculate anything else apart from amplitude?
3) By looking at both the graphs, can we claim that the wave is transverse or longitudinal and if so then why?
Frankly, as I mentioned earlier, I can't fully visualize the second graph and so, I don't have an answer to this question. Please help
