A sound wave travels at a speed of 340 m/s. If its wavelength is 2 cm, what is the frequency of the wave ? Will it be in the audible range ?

Text Solution

Verified by Experts

Speed of sound v = 340 m/s. ,Wavelength `lambda = 2 cm = 0.02 m`.
Frequency `upsilon = ?`
`v =upsilon lambda implies upsilon = (v)/(lambda) = (340)/(0.02) = 17000 Hz` = 17 kHz.
The audible range of sound wave is 20 Hz to 20 kHz.
Hence this is in the audible range.
