I wish to see a visualization of a (mechanical) wave propagating through a medium, e.g. my voice through air when I speak or waves into the depths of a glass of water (or the sea) when I dip my finger in it.
I do not wish for a visualization that shows the pressure or something similar at one point of the affected space depending on time, but an overall image. I imagine this being fairly difficult as we can't see through solid objects, but people can get creative sometimes.
I can also understand how waves can be visualized in two dimensions:
Here red can be understood as crest, dark blue as trough and azure as the "normal" state of the medium.
This image is easy enough, as I can replicate it (in poor quality) on water myself. I am aware that there is a fine difference between surface waves and transversal waves (as mentioned here), but as far as I understand, both (the latter in 2D) can be visualized with the image above. I have absolutely no idea how to generalize the image above to three dimensions.
Side note: My physical knowledge is, at best, based on school and occasionally reading wikipedia entries.
