Question

A given wave has a wavelength of 5.0 m and a frequency of 2.0 Hz. How fast is the wave moving?A.3.0 m/sB.8.0 m/sC.10 m/sD.2.5 m/s

Answer 1

Given:

The frequency of the wave is f = 2 Hz

The wavelength of the wave is

`\lambda=\text{ 5 m}`

To find the speed of the fast-moving wave.

Step-by-step explanation:

The speed of the wave can be calculated by the as

`\begin{gathered} v=f\lambda \\ =2*5 \\ =10\text{ m/s} \end{gathered}`

Thus, the speed of the wave is 10 m/s.
