How do photons mediate the electromagnetic force?
The particles that carry that force, called photons, act like love notes. They draw the protons and electrons together. When two electrons, which both have a negative charge, communicate through electromagnetism, the photons act more like hate mail. They push the electrons apart.
What idea did Richard Feynman introduce to help describe the interaction between two particles?
quantum electrodynamics (QED), quantum field theory of the interactions of charged particles with the electromagnetic field. It describes mathematically not only all interactions of light with matter but also those of charged particles with one another.
Is the electromagnetic field made up of photons?
Electromagnetic fields are made out of photons. The magnitude and direction of the electromagnetic field intensity at any point is directly proportional to the magnitude and direction of the force of the photon at that point.
Do photons interact with electromagnetic fields?
22.2. Photons do not experience the electromagnetic force themselves, and so they do not interact with each other, but the effects of electromagnetism are produced by the energy and momentum they carry. The photons that carry force are known as ‘virtual’ particles.
Do photons interact with electromagnetic waves?
They only interact with charged particles, and not with each other. That’s why photons don’t interact with magnetic fields — the photons which make up the magnetic field are not charged so other photons cannot interact with them.
How do photons create electromagnetic waves?
In energy wave theory, a photon is generated by the vibration of particles, traveling perpendicular to the direction of vibration. The photon is typically described as an electromagnetic (EM) wave, such as the image below. These are the two components of the wave (longitudinal and transverse).
