Question

A wave has a velocity of 24 m/s and a period of 3.0 s. What is the frequency of the wave?

Answer 1

The velocity is extraneous information. Frequency is the inverse of the period, thus the frequency of the wave is 1/3 Hz.

Answer 2

0.33 Hz.

Step-by-step explanation:

The frequency of a wave and its period are reciprocal, that is:

`f=(1)/(T)`

But, by hypothesis we know:

`T=3 \ seconds`

Replacing this on the definition, we have:

`f=(1)/(3 \ sec)=0.33 \ Hertz`

Therefore, the frequency of the wave is 0.33 Hz.
