which equation could be rearranged to calculate the frequency of a wave? wavelength = frequency/speed…

Explanation:

Step1: Recall wave - speed formula

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.

Step2: Rearrange the formula for frequency

We can rewrite $v = f\lambda$ as $f=\frac{v}{\lambda}$, which is equivalent to $\lambda=\frac{v}{f}$.

Answer:

C. wavelength = speed/frequency
