What is the frequency of a sound wave whose time-period is 0.005s?

Answer

200 Hz

Explanation

The relationship between the frequency and time-period of a wave is:
`f = (1)/(T)`
Here, Frequency, `f = ?` (To be calculated)
And, Time-period, `T = 0.005s`
Putting this value in the above relation, we get:
`f - (1)/(0.005)`
`f = (1000)/(5)`
`f = 200 Hz`.
Thus, the frequency of the sound wave is 200 hertz.
