Hi, I've been reading a lot today about waves and how they have both a phase velocity and a group velocity. The group velocity makes perfect sense to me, I would phrase it as the speed at which the wave is propagating. The phase velocity on the other hand is quite confusing to me. What exactly is it? How can it have a different speed than the group velocity? Don't water particles in a water wave just move up and down as the wave traverses over them?
All I know is, a water wave does not look like this by any means!:
