Question

A sound wave travels with a speed of $330m{s}^{-1}$ in air. If the wavelength of the wave is $110cm$, then frequency of the wave is ________.

Answer 1

Speed of sound in air $v=330m/s$
Wavelength $\lambda =110cm=1.1m$
Frequency of wave $\nu =\frac{v}{\lambda }$
$\therefore$ $\nu =\frac{330}{1.1}=300Hz$
