\nFor a photon, which is a massless particle, the relationship between energy (E) and momentum (p) is given by the equation E = pc, where c is the speed of light. Given the momentum p = 10 MeV\/c, the energy E is calculated by multiplying the momentum by c.
\n<\/section>\n
\nThe energy (E) and momentum (p) of a photon are related by the formula E = pc.
\n<\/section>\n
\nIn this calculation, the unit of momentum is given in a form (MeV\/c) that directly leads to the energy unit (MeV) when multiplied by c. The MeV unit (Mega-electron Volt) is a unit of energy commonly used in particle physics. 1 MeV = 1.602 x 10\u207b\u00b9\u00b3 Joules.
