An inertial observer sees a particle moving at a speed 3c/5.
November 5th, 2022
A.7 Give a very brief description of two observational tests of general relativity.
A.8 An inertial observer sees a particle moving at a speed 3c/5. It then is seen to decay into two photons. Draw an accurate spacetime diagram to illustrate the situation before and after the decay takes place.
A.9 What energies, expressed in terms of the rest mass energy of the inertial particle, would the observer in question A.8 measure for the two photons.
