Question

The velocity of sound in air is 330 m/s. Find the wavelength of sound waves if its frequency is 10 kilohertz.

Answer 1

Step 1-Given, $f=10kHz=10000Hz,v=330m/s.$where, v is the velocity of the wave, and f is the frequency.

Step 1 - Finding the speed of the wave.

We know that velocity, frequency and wavelength are related as,

$$\begin{gathered} v=f\lambda \\ \lambda =\frac{v}{f}=\frac{330}{10000}=0.033m. \end{gathered}$$

Thus, the wavelength of the wave is $0.033m$.
