Chapter 15, Problem 41A

To determine

To calculate: Speed of propagation of waves.

Answer to Problem 41A

The speed of the wave is $\underset{\_}{2\text{ m/s}}$

Explanation of Solution

Given:

Frequency of wave = $4.0\text{ Hz}$

Wavelength of wave = $0.50\text{ m}$

Formula used:

Speed of the wave is given by,

$v=f\lambda$

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

Calculation:

The speed of the wave is calculated as:

$\begin{array}{l}v=f\lambda \\ \text{ =4 Hz}\times \text{0}\text{.50 m}\\ \text{ =2 m/s}\end{array}$

Conclusion:

The speed of the wave is $\underset{\_}{2\text{ m/s}}$
