The frequency of the sound emitted by the loudspeaker is $1020\ Hz$. Calculate the wavelength of the sound wave in air in cm where its velocity is $340\ m/s$.

Here give, frequency $f=1020\ Hz$

Velocity of the wave $v=340\ m/s$

As known, velocity of the wave $=frequency(f)\times wavelength(\lambda)$

Or $340=1020\times\lambda$

Or $\lambda=\frac{340}{1020}$

Or $\lambda=0.333\ m$

Thus, the wavelength of the wave is $0.333\ m$.
