Question

The frequency of a sound wave is 150 Hz. Calculate the wavelength of sound wave. (Speed of sound is 300 m/s.)

Answer 1

Step 1-Given data

$f=150Hz,v=300m/s.$where, v is the velocity of the wave, and f is the frequency.

Step 1 - Finding the speed of the wave.

As the speed of the wave is -

$$\begin{gathered} v=f\lambda \\ \lambda =\frac{v}{f}=\frac{300}{150}=2m. \end{gathered}$$

Thus, the wavelength of the wave is$2m$.
