Chapter SH, Problem 9.2APP

To determine

To calculate: Wavelength of a wave.

Answer to Problem 9.2APP

Wavelength of the wave is $\underset{\_}{3\text{ m}}$ .

Explanation of Solution

Given:

Frequency = $5\text{ Hz}$

Speed = $15\text{ m/s}$

Formula used:

Speed is given by,

  $v=f\lambda$

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

Calculation:

Wavelength is calculated as:

  $\begin{array}{l}v=f\lambda \\ \lambda =\frac{v}{f}\\ \lambda =\frac{15\text{ m/s}}{\text{5 Hz}}\\ \lambda =3\text{ m}\end{array}$

Conclusion:

Wavelength of the wave is $\underset{\_}{3\text{ m}}$ .
