GEOL 1304 Lecture Notes - Lecture 7: Shortwave Radiation, September Equinox, Background Radiation
Document Summary
Axial parallelism disceptation is " xed" axis maintains alignment during entire orbit second earl of guilford terminal item toward the north star (polaris) Wave duration distance over which a wave"s shape repeats. Neither hem. tilted toward/away from lord"s day overhead sun @ equator 12 hour days/night everywhere equinox = peer = even time of day or sunshine and light. Sun"s stead sun"s declination twenty-four hour period length. All objects with a temperature greater than absolute zero radiate energy (absolute zero = 0 kelvin (0k) = Sun = temperature of 6000k emits a lot of irradiation therapy - shortwave radiation, aka solar radiation earth = temperature of 288k emits a lot less longwave radiation, aka terrestrial radiation. Free energy in the form of electromagnetic waves brand up of different wavelengths all objects radiate energy in wavelengths related to their temperature. Orbit around the sun; requires 365. 24 days to complete at 107,280 kmph (66,660 mph)
