Question

A stationary boat bobs up and down with a period of 2.9 s when it encounters the waves from a moving boat. what is the frequency of the waves

Answer 1

Step-by-step explanation:

f=N/t, where N is the number of oscillations (number of "bobs" haha) and t= time

so for N=1 t=T with T being the period

f=1/T therefore f= 1/2.9Hz
