Question

The frequency of the musical note F#3 is 1.85 x 102 hertz. What is its period?

Answer 1

Answer: 0.0054 s

Step-by-step explanation:

There is an inverse relation between the frequency
`f` and the period
`T` of a wave (a sound wave in this case):

`T=(1)/(f)`

Where
`f=1.85 (10)^(2) Hz`

Hence:

`T=(1)/(1.85 (10)^(2) Hz)`

`T=0.0054 s`
