how does a photon have momentum but no mass?
mihirthemega:
because at the speed of light, the mass of any particle (including photon) is not constant and is negligible
then how does it have momentum?

the momentum and mass for PHOTON is possible, BUT only when it is MOVING.
So basically a photon have 0 REST mass, but can have nonzero MOVING mass.
Hope it helps

hey but photon are never at rest?
photons *
the question is how can a photon have no mass but momentum bcuz p=mv?
yes that's why a photon can have a moving mass which is equivalent to its energy
but zero rest mass
E²=(mc²) +(pc) ²
this is correct.. not E=mc². it is actually incomplete
understand my answer what I am saying is about rest and moving masses
the moving mass of photon is still zero
no its not apply de Broglie principle
