Velocity of surface water wave

[woepriest]

Im trying to find the velocity for the surface wave on water. Its like when you throw a pebble on a small lake and there's waves.

My book tells me that all mechanical wave follows this

V = √((elastic property)/(inertial property))

But water is not compressable and this wave is a longatuidal wave I believe. I am just stuck as to where to start.

Try here: http://physics.nmt.edu/~raymond/classes/ph13xbook/node7.html

The expression shown there can fairly easily be derived from the equations of motion for an incompressible, inviscid fluid.
