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.
The wavelength of an X-ray however is one hundredth that of the light rays that you can see, at around 10Â¯Â¹Âºm. This means that they have a lot more energy. X-ray fluorescence is the emission of X-rays from excited atoms produced by the impact of high-energy electrons, other particles or a primary beam of other X-rays.
