WebSep 2, 2010 · p = 0 (because you have to add two equal and opposite momentum) so: E^2 = (mc^2)^2 --> m = E/c^2. That is: the system of the two photons have mass. Invalid application. Each photon has no rest mass and energy equal to (pc)^2. With 2 photons in opposite directions the energy is (pc)^2 + (-pc)^2 = 2 (pc)^2. Jun 30, 2008. WebOct 20, 2024 · The correct statements Photon are : 2) All photons have same amount of energy and 4) A photon is a particle of electromagnetic radiation.. A photon is tiny particle or energy packets of electromagnetic radiation. photons is a massless particle and are stable. Photons have no electric charge. They have no electric charge as well.
