Question

If the period of a given wave is 0.05 seconds, what is the frequency of the wave?A.5 HzB.200 HzC.50 HzD.20 Hz

Answer 1

Answer:

D. 20 Hz

Explanation:

The period and the frequency are related by the following equation

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

Where f is the frequency and T is the period. So, if the period T = 0.05 seconds, the frequency is

$f=\frac{1}{0.05\text{ s}}=20\text{ Hz}$

Therefore, the frequency of the wave is 20 Hz.
