Question

The period of a sound wave coming from an instrument is 0.002 seconds. What is the frequency of the sound?

Answer 1

Frequency = 1 / (period) = 1 / (0.002 sec)  =  500 Hz

Answer 2

Frequency of sound = 500 Hz

Explanation:

the formula for frequency is given by

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

T= time period

f= frequency

$f=\frac{1}{0.002}$

f=500 Hz
