The Wave Nature of Light All forms of NRG/Light have characteristic wavelengths (?) and frequency (?). Inversely related ? ? = c (the speed of light) Light visible to the naked eye exists as a tiny portion of the electromagnetic spectrum Max Planck Transfer of energy was not continuous Only came in certain values (quantized) ?E = h? h = Planck?s constant = 6.626 x 10-34 Js Packets of energy (quantum Albert Einstein Proposed that electromagnetic radiation was quantized and made up of a stream of particles Photons The dual nature of light ? = h/mv (deBroglie equation) Electrons as Waves Louis de Broglie (1924) Applied wave-particle theory to electrons electrons exhibit wave properties QUANTIZED WAVELENGTHS
