Atticus Finch, small town lawyer and widower, is arguably fiction's greatest father. Atticus parents his ten-year-old son Jem and his younger sister, Scout (6), with a calm and approachable demeanor. For a man in the 1930s American South, he is a progressive. He's against spanking, never yells, and gives his children truthful answers to difficult questions.
The form of electromagnetic radiation that is most easily used to observe fluorescence is ultraviolet radiation, as generated by a black light or UV lights. Ultraviolet is shorter than visible light in wavelength.
Fluorescence is the emission of light or photon, similar to bioluminescence and phosphorescence. However, each of them differs beyond the atomic level. Bioluminescence is when an organism emits light through biochemical means. Bioluminescence is the outcome of the oxidation of luciferin and the enzyme luciferase.
