26. 200 Lab Explain the difference between phosphorescence and fluorescence. Give an example of one. Answer Answer

27. Lab 200 Both are the absorption of energy(usually UV) with the emission of visible light. In fluorescence the object stops glowing as soon as the energy source is removed. In phosphorescence, the glowing persists for a time after the energy source is removed. An example of phosphorescence is: a glow-in-the-dark toothbrush. An example of fluorescence is: the bright white glow of dirty shoelaces under a black light.
