Help Please!

A) On a large lake a boater notes that her fishing floater rises to a position of 0.04m above rest level at t = 1.0s. Since the steady waves of the lake reach a maximum height of 0.4m, she can figure out the frequency of the waves - can you?

B) A storm wells up on the lake and the period of the waves is cut in half. As a result, the floater is found at y=0.2 m when t=1.0s. Calculate the new amplitude of the stormy waters!
