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 electromagnetic waves with shortest wavelengths are called gamma rays. The electromagnetic spectrum runs from radio waves (the longest wavelength) to gamma waves (the shortest wavelength). In increasing wavelength order, the electromagnetic spectrum is: radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays. In the visible spectrum, violet light has the shortest wavelength.
