Question

Frequency of sound wave is 20 hertz celebrates its time period

Answer 1

Error :- Calculate not celebrate*

Question

Frequency of sound wave is 20 Hz, calculate its time period.


Solution :-


Time period of a sound is just the inverse of its frequency, that is,
$t = \frac{1 }{f}$


So if frequency is 20 Hz, time =
$\frac{1}{20} = 0.05$

Answer :- Time period is 0.05 seconds.



Some Terms related to sound :-

» Amplitude :- The maximum displacement of a wave from its mean position.

» Wavelength :- The distance between two successive crests or troughs

» Time period :- The time required by a wave to complete one oscillation.

» Frequency :- The oscillations done in 1 second. It is the inverse of time period
