I am taking AS level Physics rite now, and wanted to know what exactly determines the energy of a wave. Well since I have recently learn of stationary waves(sound waves) being standing. I know that they are formed by the superimposition of the reflected waves on the incident waves. This causes the amplitude to cancel out, and become zero. So intuitively I guess the frequency decides a waves energy, because if intensity did, then in a stationary wave, the amplitudes canceling out would make the intensity nil as well(I=κA6^2), so this will make the sound stop, which it clearly does not.
So is this reasoning right?
