The energy of a light photon (E), Plank constant (h), and the frequency of the photon...
The energy of a photon of light is given by E=hf where h=6.64x10-34 J∙s is the Planck constant and f is the frequency of the light. The photoelectric effect is the principle that underlies the operation of solar cells, for example the ones in your handheld calculator. Since photons of light have energy that depends on their frequency, different colours of light have different amounts of energy. Using the relationship between frequency (f), wavelength (λ), and the speed of light...
