A pion (rest mass m0 = 135 MeV/c2) is moving with a velocity  If it decays by emitting two photons both of which move in z-direction, find their energies in unit of MeV.
    Correct answer is '22.5'. Can you explain this answer?

    Let us attach frame S' with pion In S’ frame, pion is at rest and it decays into two photon.
    According to conservation of linear momentum, each photon will have equal & opposite momentum of each photon is given by h/λ

    So, they will have equal wavelength and hence equal frequency. According to observation of energy hv + hv = m0 c2 = 135 MeV.

    for an observer in s frame, the source of radiation moves towards right with velocity 0.8 c
    In S frame 


    So, in S frame, frequency of each photon will be 
    Associated energy E = hv’ = 22.5 MeV
