'Period' and 'frequency' are reciprocals.
Either one is (1 / the other one) .

If the period is 20seconds, then the frequency is 1/(20 seconds)

= 0.05 per second

= 0.05 Hz .

The frequency of the wave is 0.05 Hz.

How do you calculate the frequency?

The frequency and period of a wave are ​inversely​ related to each other.

Given that the time period t is 20 seconds. The frequency f can be calculated as given below.

[tex]f = \dfrac {1}{t}[/tex]

[tex]f = \dfrac {1}{20}[/tex]

[tex]f = 0.05 \;\rm Hz[/tex]

Hence we can conclude that the frequency of the wave is 0.05 Hz.
