Answer:
Explanation:
In 20 seconds, membrane makes = 20 oscillations
So, In 1 second, membrane makes = 20/20 oscillations
= 1 oscillation
The frequency of this membrane is 1 oscillation per second or 1 hertz.
The sound produced by membrane will not be audible because it is an infrasonic sound (below 20Hz).
