As a high school student, I spent a summer working in a reactor. The workers used to laugh because the guides that would occasionally come through would say that the blue aura around a sample of radioactive cobalt in a bay (ie water bay) was caused by EM waves travelling faster than the speed of light in water. I believe the real cause of Cherenkov radiation is that the speed of light in the emitting medium is greater than that of the water so when the EM waves enter the water they release enery (in the form of blue light) as they assume the speed of light of the water medium. Please correct me if I should err. --------------------------------------------------------------------------- Peter Williams University of Waterloo coops like to move, and move, Microsoft Corp. and move, and move, and move,...
