If the velocity of sound in air is 330 m/s, then express the audible range of frequencies in terms of time period.


#2

Audible range of frequencies are ${ V }{ 1 }$ = 20 Hz,
${ V }
{ 2 }$ = 20000 Hz and the velocity, v = 330 m/s
So, Time period will become ${ T }{ 1 }$ = 1/ V1 = 1/20 = 5 x ${{10}^{-2}}$ s
and the time period will become ${ T }
{ 2 }$ = 1/20000 = 5 x ${{10}^{-5}}$ s
Thus, the audible range in terms of time period is from 5 X ${{10}^{-2}}$ s to 5 X ${{10}^{-5}}$ s.
