Velocity of surface water wave

  1. Jul 21, 2009 #1
    Im trying to find the velocity for the surface wave on water. Its like when you throw a pebble on a small lake and theres 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. Im just stuck as to where to start.

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

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