For any wave motion, the speed at which a wave moves equals the frequency times the wavelength.
Waves with longer wavelengths have lower frequencies.
Mathematically, we can express this as
c = f λ
where the Greek letter for “l”—lambda, λ—is used to denote wavelength and
c is the scientific symbol for the speed of light.
Solving for the wavelength, this is expressed as:
λ = c / f
