Atticus shows this in the smallest of ways, such as with the family's ornery old neighbor, Mrs. Dubose, who makes a habit of taunting Jem and Scout when they walk by her house. Just hold your head high and be a gentleman, Atticus advises Jem.
As light continues to move though the atmosphere, yellow wavelengths are scattered leaving orange wavelengths. Further scattering of orange wavelengths leaves red as the predominate color of sunlight. Therefore, near sunrise and sunset, a cloud's color is what sunlight color it receives after Rayleigh scattering.
Gamma rays have the shortest wavelengths, < 0.001 nm (about the size of an atomic nucleus). This is the highest frequency and most energetic region of the electromagnetic spectrum. Gamma rays can result from nuclear reactions taking place in objects such as pulsars, quasars, and black holes. X-rays range in wavelength from 0.001 - 10 nm (about the size of an atom).
