What is a photon?
Q: What is a photon?
A: A photon is an elementary particle that transmits light and is its own antiparticle.
Q: How does the energy of a photon depend on frequency?
A: The energy of a photon is related to its frequency, with higher frequency photons having more energy and being associated with shorter wavelengths.
Q: Who proposed that light consists of separate pieces of energy (particles)?
A: Albert Einstein proposed that light consists of separate pieces of energy (particles).
Q: What symbol is usually used to represent a photon?
A: The symbol γ (gamma) is usually used to represent a photon.
Q: Does a photon have mass?
A: No, photons have no rest mass. However, according to Einstein's theory of relativity they do have momentum.
