Question

if velocity of sound in air is 330 M per second then Express the range of audible in frequency in term of time period​

Answer 1

The audible frequency is between 20 hertz and 20000 hertz

Let frequency be √ and T denote the timeperiod

√ = 1/ Time period

√ = 1/f

for √ = 20 Hz

T = 1/ 20  sec

T= 0.05 sec

for √ = 20000 Hz

T = 1/ 20000

T = 0.00005 seconds

Therefore the range is between between 0.05 sec  to  0.00005 sec.
