EARTH 4 Lecture Notes - Lecture 18: Ultraviolet, Distress Signal, Wind Wave
Document Summary
For this wave the equation kicks in at 5 meters (1/20 the wavelength) For this to be true, the water depth has to be greater than 50 meters (not feelings. Distress signal from egypt flight sent out, emergency beacon picked up by satellites, helps them identify where to conduct a search, still no finding of black box. If l = 100, c = 1. 25 x square root of 100 = 12. 5 m/s bottom) Tsunami wave: wavelength l = 100,000m in 4 kilometers of water which is a shallow water wave so c = 3. 1 x square root of 4,000m = 196 m/s. Fetch: distance that the wind blows without interference. The earth is naturally warmed by the greenhouse effect. Greenhouse gases are increasing in the atmosphere the major culprits (co2, ch4, n2o) are anthropogenic. Climate change will have a variety of impacts on the ocean/planet. 30% of light coming from sun is reflecting (albedo)
