Answer 1

$\huge \mathfrak \colorbox{purple}{answer}$

A time period is the overall time that is required for the vibration to complete one cycle during a given point in time.

with the increase in the period,the frequency of the wave decreases.

when the time period of a wave is 0.05 second it's frequency=1/ the given time period,given time period=0.05 sec thus f = 1/0.05 =20Hz.
