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.
Most often, the emitted light has a lower energy (longer wavelength)than the absorbed light. So, most often any fluorescence we can see is produced by light withhigher energies (shorter wavelengths) than visible light. This shorter-wavelength light isultraviolet, the kind that causes sunburn.
