Index of Subjects David, This effect is common in high energy physics where particles travel near the speed of light. Light in a material travels at a speed equal to the speed of light (c) divided by the index of refraction (usually greater than one) so slower than c. A cone of light is created along the path of the particle - This is called Cherenkov Radiation. ////// === /////// Larry Bogan Brooklyn Corner, Nova Scotia <larry@bogan.ca> On Sun, 04 May 2014 10:33:09 -0300 David & Alison Webster <dwebster@glinx.com> wrote: > Dear All, May 4, 2014 > In a 1981 Popular Science I noticed the following: "When protons in > water decay, scientists believe, they produce electrically charged particles > that travel faster than lights does."; presumably speed of light in water. > Has this been verified and are there other examples where light loses > the race ? > Yt, Dave Webster, Kentville >
