Question

Your floating in the sea, measuring waves (as you do). You time 5 seconds between one crest passing and the next.


a) What is the period of this wave ?

b ) what is the frequency of this wave?

c) by watching the waves move along a breakwater you estimate that the distance that the distance between 10 crests is 30m. Calculate the average wavelength of the waves.

d) How far have the waves traveled each time a crest passes you?

e) how long does it take the wave to pass you

f ) how far does the wave travel in one second?

g) what is the speed of the wave?

h) which way do you move as the wave passes through you?
