Ocean Wave Demo

[eruheru]

Hey all,

I am trying to set up an ocean wave demonstration in a fish tank. Does anyone have any suggestion on how I could show various wave properties such as wave length, wave height, wave period, fetch etc in a tank that's about four feet long? I was thinking that there might be a way to use dyes or somesuch.

Thanks!

Perhaps liquids of varying densities would go well with your dyes.
