Question

A whale emits a subsonic sound wave with a frequency of 7 Hz. What is the period of this wave?

Answer 1

Answer:

Period of this wave, T = 0.142 seconds.

Explanation:

The frequency of the sound wave, f = 7 Hz

We need to find the period of this wave. The time period of the wave is given by :

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

$T=\dfrac{1}{7\ Hz}$

T = 0.142 seconds

So, the period of this wave is 0.142 seconds.  Hence, this is the required solution.
