THE ENERGY OF LIGHT
E = h(nu) (energy of a photon = Planck's constant * photon's frequency = hc/(lambda) = Planck's constant * speed of light * photon's wavelength) These equations give the energy of a single photon of light, and how it relates either to its frequency or its wavelength. For reference, h = 6.63 * 10^-34 Joule sec and c = 3 * 10^8 m/sec. [more text TK] |
