Question

A person notices water waves on the surface of the pond. 18 waves pass by a person in 12 seconds. Calculate the frequency of these water waves. Give the unit.

Answer 1

f = 1.5 Hz

Step-by-step explanation:

Given that,

18 waves pass by a person in 12 seconds.

We need to find the frequency of these water waves.

We know that,

Frequency = no. of waves per second

So,

`f=(18)/(12)\\\\f=1.5\ Hz`

So, the frequency of these water waves is equal to 1.5 Hz.
