Question

Find the frequency of a wave whose time period is "0.2" second.

Answer 1

frequency = 1/time period

=> f = 1 / 0.2

=>f = 1 / 2 /10

=> f = 10 / 2

frequency = 5 Hz

Answer 2

The frequency of the wave is 5 Hz.

Explanation:

The time period of a wave is 0.2 seconds. We need to find the frequency of a wave. Let f is the frequency of the wave. The total number of waves per unit time is called frequency of a wave. The frequency of a wave is also given by :

$f=\dfrac{1}{T}$

$f=\dfrac{1}{0.2\ s}$

f = 5 Hz

So, the frequency of the wave is 5 Hz.
