Heinsbergrelatz Posted March 2, 2013 Share Posted March 2, 2013 How do you solve questions like this? I really need help cause i cant get the hang of it: A neutral pion of mass 135MeV/c^2 traveling at 0.8c decays in to two photons traveling in opposite direction. What is the ratio of the frequency of photon A to that of photon B??? Link to comment Share on other sites More sharing options...
swansont Posted March 2, 2013 Share Posted March 2, 2013 You can solve the problem in any frame of reference you wish, so you choose a convenient one. Then transform into the frame given in the problem. The rest frame is a convenient one, because momentum is zero. That puts certain easily-applied constraints on the problem.

swansont Posted March 2, 2013 Share Posted March 2, 2013 In the CoM frame, what will be the energy of the photons emitted? What's their frequency? What's the ratio of the frequency of each in the frame moving 0.8c? Link to comment Share on other sites More sharing options...
