f = c / λ and λ = c / f and E = h•f (or E = h•c/ λ) (where h = Planck’s constant = 6.626068 × 10-34 m2 kg / s and c = the speed of light 3.0 x 108 m/s) From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

(Example: a solar calculator converts the energy of light shining on it to electrical energy.) In 1905, Einstein proposed that electromagnetic radiation had wavelike and particle-like natures. The photon is a particle of electromagnetic radiation with no mass that carries a quantum of energy. Ephoton = h( h = Planck’s constant
