Tsunami/physics question (movie related)

I seem to recall in Deep Impact that one of the lines said that the meteor hitting the earth would create a tidal wave several hundred metres high travelling at 1,000 mph. At that speed would it generate a sonic boom? Would portions of it boil-off due to air resistance?

[Eric Mc]

A wave may be travelling at 1,000 mph but it does not mean that the water is travelling at that speed. A wave is a "form", not a movement of actual material.

That doesn't matter if the wave is in water, air or is electromagnetic.

Do the old skipping rope flick to send a wave down the rope trick.

A whip cracking is a sonic boom, isn't it?

[IanCress]

It could be several hundred metres high, or travelling at 1000mph, but it couldn't do both at the same time.
