A simple pendulum takes $32$s to complete $20$ oscillations, what is the time period of the pendulum$?$

Time taken to complete $20$ oscillations $=32$s

Time taken to complete $1$ oscillation $=32/20$s $1.6$s

Time period of a pendulum is time taken by it to complete $1$ oscillation.

Time period of pendulum is $1.6$ seconds.
