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.
In loose diamonds or mounted diamonds, fluorescence, which refers to the photo-luminescence of a diamond, is caused by trace amounts of the element boron. This fluorescence phenomenon can be observed when the boron in a diamond is stimulated by Ultra-Violet (UV) light. Fluorescence in diamonds is a factor described on GIA, AGS, and other loose diamond graded certificates.
