Which equation shows how wavelength is related to velocity and frequency?
Nataly_w [17]

Answer:

The correct option is the option;

\lambda = \dfrac{v}{f}

Explanation:

The wavelength of a wave is the distance between two successive crests of the wave

Therefore, the wavelength, λ, is given by the fraction of the velocity, <em>v</em>, of the wave divided by the frequency, <em>f</em>, (the number of cycles that pass through a point) of the wave

Mathematically, we have;

The \ wavelength, \ \lambda = \dfrac{The \ wave \ velocity, \ v}{The \ wave \ frequency, \ f}

\lambda = \dfrac{v}{f}
