Waves and Energy transfer problem (please am desperate)
Well, this is the problem that is breaking my head
the time needed for a water wave to change from the equilibrium level to the crest is 0.18s
a) what fraction of a wavelength is this?
b)what is the period of the wave?
c)What is the frequency of the wave?
I don't really understand this problem because of the little information they give me, and the fact that when i tried to check it with my brother's answer book, the wavelength gave 1/4, but they do not give a formula or say why the WL is 1/4..
Please help me...![Cry :cry: :cry:](/styles/physicsforums/xenforo/smilies/cry.png)
