So in an equation form of will look like

No. of times an activity has happened ÷ Time taken(in seconds)

So the activity here is flapping of wings which is done 50 times and the time taken to do this activity is 20 seconds.

So the frequency = 50/20

Frequency = 2.5 times per sec

The unit of frequency is Hertz. So the frequency here is 2.5 Hertz.
