Question

If the period of a wave is 9.2 s, what is its frequency (in Hz)?

Answer 1

The period of the function is the inverse of the frequency:

⇒ (in other words)
`period = (1)/(frequency)`

Since the period is 9.2s:

`Frequency = (1)/(period)=(1)/(9.2) =0.11_.Hz`

Answer: 0.11 Hz

Hope that helps!
