Question

The period of a sound wave coming from an instrument is 0. 002 seconds. What is the frequency of the sound? Hz.

Answer 1

The period is the time taken by the wave to complete an oscillation. The frequency of the given sound is 500 Hz.

Period:

It is the time taken by the wave to complete an oscillation. The frequency is inversely proportional to the time:

$f = \dfrac 1T$

Where,

$f$- frequency

$T$ - period = 0.002 s

Put the value in the equation,

$f = \dfrac 1{0.002}\\\\f = 500\rm \ Hz$

Therefore, the frequency of the given sound is 500 Hz.
