Question

A sound wave has a speed of 340 m/s and a frequency of 1000 hz. The period of the sound is closest to?

Answer 1

Relationship Between Frequency and Period

The frequency and the period are inversely proportional.

`f=(1)/(T)` where T is the period

Solving the Question

We're given:

• v = 340 m/s
• f = 1000 Hz

Because the frequency and the period are reciprocals of each other, we can find the period of the sound by finding the reciprocal of the frequency:

`T=(1)/(1000)`

Answer

`T=(1)/(1000)`
