Question

What is the speed of periodic wave disturbance that has a frequency of 3.50 Hz and a wavelength of 0.700 m?

Answer 1

Given:

The frequency of the wave is f = 3.5 Hz

The wavelength of the wave is

`\lambda\text{ = 0.7 m}`

To find the speed of the periodic wave.

Step-by-step explanation:

The speed of the periodic wave can be calculated as

`\begin{gathered} v=f\lambda \\ =3.5*0.7 \\ =2.45\text{ m/s} \end{gathered}`

Thus, the speed of the periodic wave is 2.45 m/s
