    What is the difference between a photon and a neutrino?

    Answer:

                    A photon is one quantum of electro- magnetic radiation having zero rest mass, no charge, zero spin and no antiparticle. It has a fixed energy which depends on frequency. A neutrino is an elementary particle that accompanies a\[\beta \]-decay. It has zero rest mass, no charge and half spin. It has an antiparticle called antineutrino. It can have any energy from zero to any value permitted by the nuclear reaction. Its nature is non-electromagnetic.
