WebWe can start with our equation that relates frequency, wavelength, and the speed of light. c=\lambda \nu c = λν. Next, we rearrange the equation to solve for wavelength. \lambda=\dfrac {c} {\nu} λ = ν c. Lastly, we plug in … WebThe Speed of a Wave. A wave is a disturbance that moves along a medium from one end to the other. If one watches an ocean wave moving along the medium (the ocean water), one can observe that the crest of the wave is moving from one location to another over a given interval of time. The crest is observed to cover distance.
