what is the charge of a photon
Physical properties. A photon is massless, has no electric charge, and is a stable particle.
Is photon energy negative?
Real photons have positive energy, and since a photon is its own antiparticle, the annihilation of a real (positive-energy) photon can always be substitued in the maths of "collisions" by the creation of a (non-real) negative energy photon.
Is energy photon always positive?
But the energy of the photon emitted should always be positive which equals to the absolute value of the energy difference.
What is the energy in a photon?
The energy of a single photon is: hν or = (h/2π)ω where h is Planck's constant: 6.626 x 10-34 Joule-sec. One photon of visible light contains about 10-19 Joules (not much!) the number of photons per second in a beam.
Do photons have a positive charge?
Photons have neither negative nor positive charge. They are not matter and have no mass. They travel the speed of light when in a vacuum like in outer space (which is not a complete vacuum, really).
Is the energy of a photon positive or negative?
Re: Is a photon positive, negative or neutral? A photon is neutral. A photon can be produced by acceleration of an electron (eg visible light) or a proton (eg gamma rays), but these charged particles retain their electric charge, and the neutral photon carries away some energy released in the event.
Are light photons positive or negative?
A photon is neutral. A photon can be produced by acceleration of an electron (eg visible light) or a proton (eg gamma rays), but these charged particles retain their electric charge, and the neutral photon carries away some energy released in the event.
Why do photons have no charge?
A charged particles produced electric field which in turn produces a magnetic force. If there is a change in electromagnetic field that change will be propagated in waves. … So photons don't carry any electric field and thus no charge.
Can light be charged?
It does not itself carry a charge. Light does not have a charge. "Charge" is just what we call the tendency of something to affect and be affected by electromagnetic fields, which are what light is made of. The reason positive and negative charges are attracted to each other is that they both give off these fields.
Does a photon have charge and mass?
A photon is an electromagnetic wave, so it does not have mass. We know that a particle having some charge needs to have mass. That is why a photon does NOT have any charge.
Do light photons have charge?
All photons travel at the speed of light. Considered among the subatomic particles, photons are bosons, having no electric charge or rest mass and one unit of spin; they are field particles that are thought to be the carriers of the electromagnetic field.
Does photon have charge?
All photons travel at the speed of light. Considered among the subatomic particles, photons are bosons, having no electric charge or rest mass and one unit of spin; they are field particles that are thought to be the carriers of the electromagnetic field.
Does a photon particle have mass?
Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum. … But an object with zero energy and zero mass is nothing at all. Therefore, if an object with no mass is to physically exist, it can never be at rest.
How come photons 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.
How much mass is in a photon?
According to electromagnetic theory, the rest mass of photon in free space is zero and also photon has non-zero rest mass, as well as wavelength-dependent. The very recent experiment revealed its non-zero value as 10 – 54 kg ( 5.610 × 10 – 25 MeV c – 2 ) .
Does a photon have charge and mass?
A photon is an electromagnetic wave, so it does not have mass. We know that a particle having some charge needs to have mass. That is why a photon does NOT have any charge.
Why does a photon have no charge?
A charged particles produced electric field which in turn produces a magnetic force. If there is a change in electromagnetic field that change will be propagated in waves. … So photons don't carry any electric field and thus no charge.
Can a photon be charged?
Physical properties. A photon is massless, has no electric charge, and is a stable particle.
Why are photons neutral?
It exists because there is a field. … To put simply, the particle-like interpretation of the electromagnetic field involves photons which are particles constituting and Electromagnetic field. In that case they are neutral electrically.
Is a photon positively charged?
Photons have neither negative nor positive charge. They are not matter and have no mass. They travel the speed of light when in a vacuum like in outer space (which is not a complete vacuum, really).
Why are photons not charged?
A charged particles produced electric field which in turn produces a magnetic force. If there is a change in electromagnetic field that change will be propagated in waves. … So photons don't carry any electric field and thus no charge.
