The speed of light slows in water.
I would say yes. As soon as the wave stops being a wave in shallow water then becomes a crest; bending.
refraction
It is a damped harmonic motion.
the waves travel through water, but they do not carry the water with them. The ship moves up and down as the wave passes under it. The ship does not travel with the wave!
The buoy moves up and down as the water passes beneath it.
The wave travels through the water without moving the water with it (the water moves but then as the wave passes the water moves back to where it was). The floating leaf stays with the water as the wave passes on its way to the shore.
The cork will move up and down with the wave, since the wave is a transverse wave. I would think that the frequency should be the same as the wave.
As an ocean wave passes, the water moves up and down in a circular pattern and returns to its original position.
The speed at which a wave passes through water or other medium is called phase velocity.
Shallow water is more dense than Deep water. This means that a wave travelling from deep water to shallow water would bend towards the normal. Also, the wave would travel slower in the shallow than in the deep water
When a wave passes through the ocean it may make a wave.
That's because the water doesn't move, either. The water moves back and forth slightly, as a result of the wave; the wave energy moves on, WITHOUT taking the water with it. The wave is not a current.
