Document Summary
Chlorophyll, indigo are both common with a conjugated system. Gamma rays have more energy, have shorter wavelength. Blue light has more energy than red light bc shorter wavelength. Gamma rays < x rays < ultraviolet radiation < near-infrared radiation < microwaves < radio waves. Visible light= narrow region of entire em spectrum. Light behaves like a wave: short wavelength (gamma rays) vs long wavelength (radio waves) Em spectrum is separated based on wave length. Energy of the light is inversely related to wavelength *** Light as discrete particles of quanta; quanta blue light, quanta of red light. Quanta aka photons (have a discrete, quantifiable amount of energy) In order to use energy, must absorb light. Conjugated system: alternation between a double to single bond; indicates a specific kind of electron configuration many nonbonding electrons (pi orbital electrons) Nonbonding electrons will interact with photons of light; not required for bonding thus readily accessible to track energy.
