1. The problem statement, all variables and given/known data Well it's not so much a direct question as it is several. I'm very confused about sound waves. I know that, when modelled as a transverse wave on a set of axis, a compression is a maximum and a rarefaction is a minimum. But where do nodes and antinodes fit into this? Which is a node, which is an antinode? What's more, I'm even more confused about actual loud points. Are compressions and rarefactions considered to be loud points, meaning the point in the middle is a quiet point? 3. The attempt at a solution See attached image. You can see that I had a go at labelling the wave myself. Could someone please replace my labels with the correct ones? Thanks very much.
