How can light have momentum if it has no mass?

In short, even 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.

How can a photon have no mass?

Why do photons have no mass? In short, the special theory of relativity predicts that photons do not have mass simply because they travel at the speed of light. This is also backed up by the theory of quantum electrodynamics, which predicts that photons cannot have mass as a result of U(1) -gauge symmetry.

What particle has no mass?

The two known massless particles are both gauge bosons: the photon (carrier of electromagnetism) and the gluon (carrier of the strong force). However, gluons are never observed as free particles, since they are confined within hadrons. Neutrinos were originally thought to be massless.

Which particle does not have mass?

photon
In particle physics, a massless particle is an elementary particle whose invariant mass is zero. The two known massless particles are both gauge bosons: the photon (carrier of electromagnetism) and the gluon (carrier of the strong force).

Why does light carry energy without mass?

Light indeed carries energy via its momentum despite having no mass. Public Domain Image, source: Christopher S. Baird. Light indeed carries energy and accomplishes this without having any mass. The Einstein equation that you are probably referring to is E= mc2. This equation is actually a special case of the more general equation:

Is light massless yet it can exert force?

$\\begingroup$It looks that you already know the answer to your question: yes, light is massless yet it can exert a force. Maybe your question should be “how is this possible?”, right?$\\endgroup$

What is the mass of light on the basis of Physics?

So light has mass on the basis of Newton’s gravitational law. its mathematical interpretation is hinted below: By the newton’s universal law of gravitation, F=G (M1*M2)/R^2 where, m1=mass of heavenly body r=distance f=gravitational force m2=0=mass of light If the mass of light is o then gravitational force would not be there.

Why can photons move with the speed of light?

Since photons have zero rest mass they can move with the speed of light. MASS OF LIGHT IS NOT 0. Light has mass. Generally,Mass is defined as the amount of substance or matter contained in the body.
