Speed (c) is related to frequency (f) and wavelength (λ) by the equation: c = λ * f Since the speed on the left side of the equation is always constant, that means that as wavelength goes down, the frequency must go up. The shorter the wavelength (as we move to the right on the spectrum) the higher the frequency.
