Last night an EE I was talking to here in San Diego got noticeably upset with me when I asserted that all visible light consists of photons, including light from such sources as the sun, an electric spark, and a lit match. I found myself being treated like a crackpot for asserting what I took to be the most trivial and accepted tenet of Quantum Physics, that all visible light consists of discrete bundles of energy called "photons". His claim was that all the light sources I mentioned emitted "radiant energy", which did not consist of photons. "True" photons, he angrily insisted, were only emitted in the special case where electrons were bouncing in and out of "holes" such as you find in a light emitting diode. Scowling and growling at me, he advised me to google "photonic energy", to be enlightened. He's an EE and I'm not, so is there really only an authentic special case "true" photon, as he asserts?
