Document Summary
The amount of energy that a blackbody (objects that absorb and emit radiation uniformly and with 100% efficiency) emits is proportional to the fourth power of its absolute temperature: wein"s law. The wavelength of the peak radiance decreases linearly as the temperature increases. The warmer the body, the shorter the wavelength. The cooler the body, the longer the wavelength: combing sb & w"s laws: Causes rainbows: energy pathways: short wave in and long wave out (aka insolation) Direct radiation: form sun, through atmosphere, doesn"t get reflected/absorbed/scattered, hits earth"s surface, casts a shadow. Diffuse radiation: scattered, you do not have shadows. The earth gives off long-wave radiation: because we have clouds, some of that will get re-reflected back down to surface, clouds will deflect radiation back to space (cid:2) Different parts of the surface of the earth have different colors/levels of albedo. Albedo is represented as a percent of reflection (cid:2)
