1. The problem statement, all variables and given/known data

Find Wavelength and Velocity of an Ocean Wave.

Known Variables:
Water Depth=300m
Frequency=8secs
Amplitude=3m

2. Relevant equations
Wavelength (m) X Frequency (s-1) = velocity (m/s)

v=velocity

3. The attempt at a solution

I have 2 missing variables for both of the above equations.
Am I missing a variable or equation?

Thanks.

To find the wavelength of an ocean wave you just need to measure from crest to crest.

If you replace $$\lambda$$ in your equation according to
$$\lambda = \frac{v}{f}$$ where f is known
you will have an equation with only one unknown, v.
However this equation cannot be solved analytically but only by numerical methods.
