Chapter 14, Problem 104A

To determine

Frequency of the spring’s oscillation.

Answer to Problem 104A

Frequency is $3\text{Hz}$ .

Explanation of Solution

Given:

Velocity of the wave, $v=\text{5}\text{m/s}$

Wavelength of the wave, $\text{λ=1}\text{.5m}$

Formula Used:

Frequency can be obtained by:

  $f=\frac{v}{\lambda }$

Where $f$ is frequency , $v$ is velocity and $\lambda$ is wavelength

Calculation:

Substitute the values and solve:

  $f=\frac{v}{\lambda }$

  $\begin{array}{l}\text{=}\frac{\text{5m/s}}{\text{1}\text{.5m}}\\ \text{=3Hz}\end{array}$

Conclusion:

Hence, the frequency of the spring’s oscillation is $\text{3Hz}$ .
