In what ways photons resemble other particles such as electrons and what way do they differ and whether the photons have mass and electric charge. Also determine if photons can be accelerated and their mechanical properties.
Answer to Problem 1DQ
Explanation of Solution
The packages of
Photons are elementary particle that are force carriers of electromagnetic force. Electron are fundamental particles but are not force carriers rather constituents of matter. Both electron and photon exhibit wave-particle duality and are quantum particles. Electrons are charged while photons are charge less.
Photons have zero rest mass. They move with a constant velocity given by
Conclusion:
Thus, photons are elementary particles like electrons but are force carriers and not part of matter. Photons have zero rest mass and are charge less particles. Photons cannot be accelerated in the local frame and have momentum and energy proportional to the frequency.
