Wave speed and water depth.
I have trouble understanding why water waves tend to speed up for waters deeper than 1/2 wavelength and slow down for waters shallower. I have read it has something to do with how the particle orbit changes to elliptical in shallow waters.
Why does the particle orbit become a flat ellipse in shallow water and is that the factor influencing the slower wave speed? If not not, what is?
Re: Wave speed and water depth.
Does anyone have an answer for this?
