Explain using an equation (or equations) given above. Higher wavelengths correspond to a higher energy of electromagnetic waves (light). This is determined using Planck’s equation with the equation v = i Energy of the light is proportional to its wavelength. 3) Which end of each series corresponds to the higher frequency light: the higher or lower wavelength? Explain using an equation given above. The higher frequency of light is on the end with the shortest wavelengths. Again, using the equation v = % , frequency and wavelength are inversely proportional. So the bigger the wavelength, the smaller the frequency.
