In color films, there are separate layers of photosensitive emulsion for each of the three primary colors of emitted light (red, blue, and green). the process of film exposure is again based on absorption of light energy, but now each layer is treated to react to only one-third of the spectrum. for example, the red-sensitive emulsion is specially treated to react to light only in the portion of the visible spectrum that includes longer wavelengths. when a single photon of energy 2.89×10−19 j strikes a color film, in what layer of emulsion will it be absorbed?
