Document Summary
Travels in waves/ travels in terms of a particle. The distance between the crest determines what type of light it is. Wave-particle duality, behaves like a particle but travels like a wave. When light is absorbed it raises the electron to an excited state (further away from. They have kinetic energy and even in physical visible light have longer lengths. Inverse to the amount of energy, high energy = shorter wave lengths. Light has no mass but interacts with matter which has kinetic energy. Light of a particular wave length will bounce off and be seen as colour or visible light. Light may bounce off, transmit through or be absorbed. Alternating single bond called a conjugated system because of the structure. Chlorophylls can absorb light at different wave lengths. Colour is the light that is not absorbed, everything transmitted through we see. Comes from photosynthesis, rotation of carbon dioxide being reduced to produce.
