PHYS 161 Lecture Notes - Lecture 16: Radiative Equilibrium, Problem Set, Irradiation
Document Summary
Note: if you want to double thermal energy you need to measure it in k. so you should always measure thermal energy in k if possible. Time scale for equilibrium is on a time scale of months (not sec or century"s) If you increase the radius of the earth by 3 . So the tempeture of the earth does not depend on it size(the radius). More realistic modellonly7-% of the sun"s power is absorbed by the earth (albedo= . 3) The green house effect (look at study guide #8) Triatomic (and larger) molecure shave intramolecular: motions (vibration rotation, bending) that can be excited by infrared electromagnetic waves. Two kids holding hands can wiggle but are easy to avoid. Three kids can twist and turn making it easer to capture other molcules (children). Co2isanecessaryproduct of fossil fuel combustion. (we"ll discuss water soon) An atmosphere that absorbs more ir necessarily leads to a higher temperature fro the earth(radiative equilibrium).
