Question

What is the frequency of a wave that has 3 waves every five seconds?

Answer 1

Answer:

Frequency, f = 0.6 Hz

Explanation:

We have,

Number of waves passing through a point are 3

Time for which the waves are passing is 5 seconds

It is required to find the frequency of a wave. The frequency of a wave is defined as the no of waves per unit time. So,

$f=\dfrac{n}{t}\\\\f=\dfrac{3}{5}\\\\f=0.6\ Hz$

So, the frequency of a wave is 0.6 Hz.
