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!
What else can I help you with?
Which particle has the least amount of mass?
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 sentence for photon?
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?
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.
How does a photon differ from a material particle?
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.
A photon of wavelength 3000 A is absorbed by a gas and remitted as two photons One of the photons is red 7600 A What is the wavelength of the other photon?
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.
What is the mass of moving 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.
What is the plot mass of photon?
the photon has got 0 rest mass .and plot mass means? not knowing..
mass of photon?
Photons have no mass.
What is the mass of one photon?
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!
Is it possible to have a particle with zero rest mass but still possessing momentum?
Yes. That's exactly the case with the photon, the particle of electromagnetic energy.
What is the smallest in mass?
A photon.
What subatomic particles have a mass of 0?
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.
What is the mass of a photon in motion?
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).
Which is not the property of photon mass charge energy momentum?
A photon has zero electrical charge.
When can a substance's mass be 0?
Yes, a Photon's mass is theorized to be zero.
What is the mass of gamma in atomic mass units?
If you mean a gamma photon, it is mass-less.
What do you call a particle of light with zero mass which carries a quantum of energy?
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.
