Do photons have an atomic nucleus with protons and neutrons and electrons? Does spin effect charge? Anything? Why do photons travel at c? Where do they get this power to travel at c from?
Photons are fundamental particles; they do not have any internal composition, and cannot be broken down into smaller pieces.
A photon is a fundamental particle of light that carries electromagnetic energy. It has zero mass and travels at the speed of light.
The properties of a photon include its energy, wavelength, frequency, and polarization. It also has spin, angular momentum, and momentum.
A photon can be created through various processes such as emission from an excited atom or electron, nuclear reactions, or particle collisions.
Photons are the basic units of light. They are emitted, absorbed, and scattered by matter and carry the energy of light.
Yes, photons can be detected using specialized instruments such as photomultiplier tubes or photodetectors. These devices convert the energy of photons into an electrical signal that can be measured.
