Question

A boat at an anchor is rocked by waves whose crests are 100 m apart. The wave velocity of the moving crest is 20m/s. What is the frequency of rocking of the boat?

Answer 1

velocity =frequency *wavelength
velocity=20m/s
wavelength =100m
frequency =??
frequency = velocity/wavelength
frequency =20/100
frequency = 0.2 hz

Answer 2

Answer:

The boat's rocking frequency is 0.2Hz

Explanation:

Given

Wave length λ=100m

Velocity ν=20m/s

Formula used

               f=ν/λ

Solution

               f=ν/λ

               f=20/100=0.2Hz
