Question
Calculate the frequency of a wave whose time-period is 0.02 s.
Solution
We have to find the frequency of oscillation.
Given: Time period T = 0.02 s
We know the relation between frequency and time period `f = 1/T` .
where f is the frequency and T the time period.
So,
`f = 1/0.02` Hz
= 50 Hz
