Question

Frequency and period are closely related. Frequency is the inverse of period. If the time it takes for a full wavelength to pass is 5 seconds, what is the frequency of the wave?

Answer 1

The relation between the frequency and the time period is

`f=(1)/(T)`

Here, T is the time period.

Now, given the time period is 5 seconds.

The frequency of the wave is

`\begin{gathered} f=\frac{1}{5\text{ sec.}} \\ f=0.2\text{ Hz} \end{gathered}`

Thus, the frequency of the wave is 0.2 Hz.
