What is the frequency (f) of a wave with a period of 0.04 seconds?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is  option 3  i.e. 25 Hz.

The frequency (f) of a wave is the reciprocal of its period (T). That is,

f = 1T \frac{1}{T}

Given: T = 0.04 seconds

So, f=10.04=25 Hz f = \frac{1}{0.04} = 25 \text{ Hz}

The frequency of the wave is 25 Hz.
