Question

Water ripples are produced by making a cork oscillate up and down at a frequency of 5 Hz. The peaks of the ripples are 0.03 meters apart. What is the speed of the water ripples?

Answer 1

Answer:

The speed of water ripples, v = 0.15 m/s

Explanation:

It is given that,

Water ripples are produced by making a cork oscillate up and down at a frequency of 5 Hz, f = 5 Hz

The peaks of the ripples are 0.03 meters apart, $\lambda=0.03\ m$

We need to find the speed of the water ripples. The speed of water ripple is given by :

$v=f\times \lambda$

$v=5\ Hz\times 0.03$

v = 0.15 m/s

So, the speed of water ripples is 0.15 m/s. Hence, this is the required solution.
