I read that the speed of a tsunami is given by
c = sqrt(G * d)
where G is the gravitational constant 9.8 m/sec^2 and
d is ocean depth in meters.
How is this derived? I had always thought that wave speed was a constant depending only on the medium.
Also, is there some fundamental mechanical difference between a tsunami and a "normal" surface ocean wave?
