Size of a photon

WebbThe chromophore absorbs photons of light, using a mechanism that involves a change in its configuration. In vertebrate rods the chromophore is retinal, the aldehyde of vitamin A 1. When retinal absorbs a photon, the double bond between the 11th and 12th carbon atoms flips, thus reconfiguring the molecule from the 11-cis to the all-trans form. WebbNormally, if you ask a physicists how big as a photon, they will tell you the wavelength of light. Say 550 nm for yellow light. This is more than a thousand times bigger that the typical atom. So when light passes through glass, it is bent …
