Question

The range of the frequency of audible sound is 20 kHz. What is the range of wavelength for the audible sound at $0^{\circ }C$? (Take velocity of sound as ${330ms}^{-1}$ at $0^{\circ }C$)

Answer 1

Velocity of sound $v=330m/s$

Range of audible frequency $\nu =20000$ Hz

Wavelength of sound $\lambda =\frac{v}{\nu }$

Range of wavelength of audible sound $\lambda =\frac{330}{20000}=16.5mm$
