Question

What is the frequency of a wave that has a wavelength of 4.72 m and travels at 50.0 m/sO 236 Hz0.0944 Hz10.6 Hz45.3 Hz

Answer 1

3rd option: 10.6 Hz

Explanation:

Given:

Wavelength (λ) = 4.72 m

Speed (v) = 50 m/s

We calculate the value of the frequency using the following formula:

`\begin{gathered} v=\lambda\cdot f \\ \\ \text{ we replacing} \\ \\ 50=4.72\cdot f \\ \\ f=(50)/(4.72) \\ \\ f=10.6\text{ Hz} \end{gathered}`

The frequency is equal to 10.6 Hz, therefore, the correct answer is 3rd option: 10.6 Hz
