Homework Statement



Use Buckingham's Pi Theorem to describe waves amplitude.

The Attempt at a Solution



Waves amplitude depends on:
Geometric variables: L,A
Kinematic variables: g,c (c = waves speed)
Dynamic variables: roh (density), sigma (surface tension)

Using MLT:
L = L, A = L2, g = L/T2, c = L/T, roh = M/L3, sigma = ML2/T2

Pi terms = n - m = 6 - 3 = 3 Pi terms

I'm not sure if I've choosed all involved variables?! And what to do with repeating variables?! I don't even know how to apply the theroem if I have to find more than one Pi?!

Thanks for your help! :)
