Question

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

Answer 1

We know that frequency is an inverse value of time $f=\dfrac{1}{t}$ this implies that time is the inverse value of frequency $t=\dfrac{1}{f}$.

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

$t=\dfrac{1}{40\mathbf{kHz}}=0.000025\mathbf{s}=25\mathbf{\mu s}$

Hope this helps.
