WebEven though photons have no mass, they still have momentum proportional to their energy, given by the formula p=E/c. Because photons have no mass, all of the momentum of a photon actually comes from its energy and frequency as described by the Planck-Einstein relation E=hf, and NOT E=MC squared. 3 UntangledQubit • 1 yr. ago WebLight carries energy due to its momentum resulting from its speed. It doesn’t carry energy due to its mass. Mass and momentum are two separate factors that give an object or a particle it’s energy. If there is zero mass then the energy would be from its momentum. If the momentum is zero then the energy would be from its mass.
