The time needed for a water wave to change from the equilibrium level to the crest is 0.20 s.
(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 understand any of this. help appreciated

Think of the graph of a sine wave.
one period of the wave proceeds as follows
equilibrium → maximum → equilibrium → minimum → equilibrium
Each stage is 1/4 of the period. So,
(a) 0.20 s = 1/4 of the period T
(b) T = 4*0.20 = 0.8 s
(d) f = 1/T = 1.25 Hz
