When one of these particles has an energy greater than 1.022 mega electron volts and is next to a nucleus, it can convert its energy to mass.
This particle is the only massless gauge boson that is created by the Higgs mechanism. When one of these particles has an energy greater than 1.022 mega electron volts and is next to a nucleus, it can convert its energy to mass. When this particle is scattered, its change in wavelength is proportional to 1 minus the scattering angle, according to the formula for Compton scattering. These particles, which create electron-positron pairs in pair production, make up X-rays and gamma rays. The photoelectric effect shows how light can be modelled both as waves and as these particles. For 10 points, name this particle that is the quantum of the electromagnetic force.
