**1. Homework Statement**

The speed of waving in shallow water depend only on the acceleration of gravity g, a quantity with dimensions L/T^2, and on the water depth h.

Which of the following formulas for the wave speed v could be correct?

a) v=1/2gh^2 b)v=√gh

**2. Homework Equations**

L = [tex]\frac{n\lambda_{n}}{2}[/tex]

v[tex]^{2}[/tex] = [tex]\frac{T}{\frac{m}{l}}[/tex]

v = f[tex]\lambda[/tex]

**3. The Attempt at a Solution**

I think I have to use one of above equations, but I don't know where to start.
