Question

which process would correctly calculate the frequency of a wave?
dividing speed by wavelength
dividing frequency by wavelength
multiplying frequency by period
dividing wavelength by period

Explanation:

The wave - speed formula is $v = f\lambda$, where $v$ is the speed of the wave, $f$ is the frequency, and $\lambda$ is the wavelength. Rearranging for frequency gives $f=\frac{v}{\lambda}$.

Answer:

A. dividing speed by wavelength
