Chapter SH, Problem 9.1APP

To determine

To calculate: Wavelength of a wave.

Answer to Problem 9.1APP

Wavelength of the wave is $\underset{\_}{0.04\text{ m}}$ .

Explanation of Solution

Given:

Frequency = $0.4\text{ kHz}$

Speed = $16\text{ m/s}$

Formula used:

Speed is given by,

  $v=f\lambda$

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

Calculation:

Wavelength is calculated as:

  $\begin{array}{l}v=f\lambda \\ \lambda =\frac{v}{f}\\ \lambda =\frac{16\text{ m/s}}{0.4\times 1000\text{ Hz}}\\ \lambda =0.04\text{ m}\end{array}$

Conclusion:

Wavelength of the wave is $\underset{\_}{0.04\text{ m}}$ .
