Question

A sound wave has a frequency of 3.395 Hz and a wavelength of 1.4 m in a certain medium. What is the speed of the wave in that medium?

Answer 1

Answer:

4.753 m/s

Explanation:

We know that the sound wave has a frequency of 3.395 Hz and a wavelength of 1.4m and we need to find the speed of the wave.

The speed of the wave can be calculated as:

$v=\lambda\cdot f$

Where λ is the wavelength and f is the frequency of the wave.

So, replacing λ by 1.4 m and f by 3.395 Hz, we get:

$\begin{gathered} v=1.4\text{ m (3.395 Hz)} \\ v=4.753\text{ m/s} \end{gathered}$

Therefore, the speed of the wave in than medium is 4.753 m/s
