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?

Respuesta :

The relation between the frequency and the time period is

[tex]f=\frac{1}{T}[/tex]

Here, T is the time period.

Now, given the time period is 5 seconds.

The frequency of the wave is

[tex]\begin{gathered} f=\frac{1}{5\text{ sec.}} \\ f=0.2\text{ Hz} \end{gathered}[/tex]

Thus, the frequency of the wave is 0.2 Hz.
