Variable wavelength (distance between 2 peaks) and energy. Different wavelengths of light have different energy. Shorter wavelength ------------ higher energy longer wavelength ------------ lower energy. Absorbed by electrons (electrons can absorb photons) Common pigments have long carbon chains and alternating single and double bonds don"t have to memorize common pigments, but should be able to tell that something is a common pigment by looking at the structure. * all life on the planet depends on these two processes. All of us rely on light as a source of information for a variety of reasons.
