Question

Calculate the wavelength of a sound wave whose frequency is $200Hz$ and speed is $440m/s$ in a given medium.

Answer 1

Step 1: Given data.

Frequency, $f=200Hz$

Speed, $v=440m/s$

Wavelength, $\lambda =?$

Step 2: Calculate the frequency.

The wavelength can be calculation by the equation as shown below:

$\begin{array}{rcl}\lambda & =& \frac{v}{f}\\ & \Rightarrow & \lambda =\frac{440m/s}{200Hz}\\ & \Rightarrow & \lambda =2.2m\end{array}$

Hence, the wavelength of the sound wave is $2.2m$.
