Chapter SH, Problem 10.2APP

To determine

To calculate: Wavelength of a sound wave.

Answer to Problem 10.2APP

Wavelength of the wave is $\underset{\_}{\text{11}\text{.8 m}}$ .

Explanation of Solution

Given:

Frequency = $\text{440 kHz}$

Speed = $\text{5200 m/s}$

Formula used:

Speed is given by,

  $v=f\lambda$

where f is frequency and $\lambda$ is wavelength.

Calculation:

Wavelength is calculated as:

  $\begin{array}{l}v=f\lambda \\ \lambda =\frac{v}{f}\\ \lambda =\frac{\text{5200 m/s}}{\text{440 Hz}}\\ \lambda =11.8\text{ m}\end{array}$

Conclusion:

Wavelength of the wave is $\underset{\_}{\text{11}\text{.8 m}}$ .
