Question

Find the period of a wave with a frequency 40 kHz​

Answer 1

We know that frequency is an inverse value of time
`f=(1)/(t)` this implies that time is the inverse value of frequency
`t=(1)/(f)`.

Now since f is 40kHz, we can calculate period or duration for that matter time.

`t=\frac{1}{40\mathbf{kHz}}=0.000025\mathbf{s}=25\mathbf{\mu s}`

Hope this helps.
