Question

A periodic wave having a frequency of 5.0 hertz and a speed of 10 meters per second has a wavelength of?

Answer 1

`\begin{equation*} 2.0\text{ }m \end{equation*}`

Step-by-step explanation

To find the wavelength of the wave, apply the formula for the speed of a wave:

`v=\lambda *f`

where λ = wavelength

f = frequency

Therefore, by substituting the given values into the equation and solving for λ, the wavelength of the wave is:

`\begin{gathered} 10=\lambda *5 \\ \Rightarrowλ=(10)/(5) \\ λ=2.0\text{ }m \end{gathered}`

That is the answer.
