Q.28. Velocity of sound in steel is 5000 . A sound wave of frequency 1000 Hz is produced in a steel rail of length 20 m. Calculate total number of waves produced in the rail.
[14 Waves]
Dear Student ,
Here in this case , n = 1000 Hz and V = 5000 m/s
So the wavelength is ,
So the number of waves produced in 20 m length of the steel rail is = 20 /5 = 4 nos.
Regards
