GEOG 101 Lecture Notes - Lecture 5: Background Radiation, Refraction, Evaporation
Document Summary
The uneven distribution of energy is responsible for driving earth"s dynamic systems. Transmission of energy (the passage of energy through atmosphere or water) May not have the ability to produce shadows. In the arctic brightness makes it difficult to see bumps or depressions on walkways. Changing direction of light"s movement, without altering its wavelengths. Changes the direction and the speed of light wavelengths. Link between path length, scattering, blue skies and red sunsets. Whenever light passes from one medium to another (e. g. Empty space to the atmosphere or from air to water) there is a change in peed and direction. The greater reflectance the higher the albedo. The darker the surface, the greater the absorption. The lighter the surface, the greater the reflectance. Energy travelling through air or space (no medium required) 0 degrees kelvin no heat whatsoever. Heat spontaneously transfers to warm or cold surfaces.
