A sound wave has a frequency of 5kHz and wavelength of 25cm.How much distance will it travel in 5 seconds?
Thus, distance= speed x time= 1250 x 5 m= 6250 m= 6.25 km
(1) Sound wave has frequency 320 Hz and wavelength 0.25 m. How much distance will it travel in 10 second.
[Ans : 800 m.]
(2) A sound wave having certain frequency travels with a speed of 336 m/s and wavelength 3 cm. calculate the frequency. Will it be audible?
[11200 Hz, Yes.]
