photons are particles of light, or waves. since they don't interact with the higgs field, they go at the speed of light. if something doesn't interact with the higgs field, it has no mass, and no mass means they go at the speed of light. for a good and cool version of this answer, go see on YouTube: The large hadron rap!
The 'rest mass' of the photon is zero ... but the photon is never at rest, and it has plenty of mass at the speed of light, at which it is always traveling. so that let's the photon out. Amongst particles that actually have rest mass, but not much of it, the neutrino probably has the least.
A photon is a sub atomic particle is a single enery packet of light As it has no mass it can travel at the speed of light (since it is light) and are created when an electron makes a quantum leap inside an atom.
The carbon-12 atom is assigned a relative mass of exactly 12 atomic mass units (amu). This is used as the reference point for measuring the atomic masses of other elements on the periodic table.
A photon is a discrete particle (having zero mass, zero charge, and an indefinate life span explainable only by quantum physics) and can travel at the speed of light; a "material particle" can only travel at speeds lower than the speed of light.
The total energy of a photon with a wavelength of 3000 A is divided into two photons, one red photon with a wavelength of 7600 A, and another photon with a shorter wavelength. To calculate the wavelength of the second photon, you can use the conservation of energy principle, where the sum of the energies of the two new photons is equal to the energy of the original photon. This will give you the wavelength of the other photon.
A photon is a massless particle, so it does not have a rest mass. It only possesses energy and momentum, but in the context of special relativity, mass is not a property of a moving photon.
the photon has got 0 rest mass .and plot mass means? not knowing..
Photons have no mass.
mass of the proton is 0. Answer 2 But the question asked about photons, not protons. The mass of a photon is also 0, though the mass of a proton is not!
Yes. That's exactly the case with the photon, the particle of electromagnetic energy.
A photon.
The photon. This refers to the "rest mass"; since the photon has energy, it also has an associated mass. But the "rest mass" or "invariant mass" is zero.
It's (double the photon's energy) divided by (the speed of light squared). The photon's energy depends on its frequency, and is (frequency) times (Planck's konstant).
A photon has zero electrical charge.
Yes, a Photon's mass is theorized to be zero.
If you mean a gamma photon, it is mass-less.
I call it a 'photon'.By the way, the photon has zero rest mass, but when it travels at the speed of light ...which it always does ... it has some mass.
