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.
Fluorite typically glows a blue-violet color under shortwave and longwave light. Some specimens are known to glow a cream or white color. Many specimens do not fluoresce. Fluorescence in fluorite is thought to be caused by the presence of yttrium, europium, samarium [3] or organic material as activators.
