Cherenkov radiation speed
WebCherenkov radiation, when it is intense, appears as a weak bluish white glow in the pools of water shielding some nuclear reactors. The … WebJan 6, 1990 · In certain media the speed of light is lower than in a vacuum and particles can travel faster than light. One result of this was discovered in 1934 by Pavel Cherenkov, when he saw a bluish light around a radioactive preparation placed in water. Igor Tamm and Ilya Frank explained the phenomenon in 1937.
