A Tennis Ball Analogy

a: Fluorescence ~
b: throwing a tennis ball against the wall

What: Fluorescence is the result of light energy hitting electrons on a molecule, raising them to a higher state, and then as the electrons fall to a lower energy state, they emit light energy that is of a higher wavelength and lower energy state. This affect is scene often on clothing treated with optical brighteners. To use a ball analogy, it's like throwing a tennis ball against a wall. The collision with the wall transforms the tennis ball into a basketball. The larger basketball then bounces off in some other direction.
