Question

Explain electrons and photons.

Answer 1

Electron:

1. An electron is a subatomic particle. A sub-atomic particle is part of the atom.
2. An electron is a negatively charged particle that has a charge magnitude of $1.6\times {10}^{-19}C$.
3. It has a rest mass equal to $9.11\times {10}^{-31} \mathrm{kg}$.
4. A moving electron exhibits wave-like property according to the dual nature of matter.
5. Electrons can interact with matter.

Photon:

1. Photon is the light particle. The energy of photons depends on the frequency of light.
2. The rest mass of the photon is zero but it has a non-zero mass when it moves, so it interacts with matter as well.
3. Interference and compton scattering are some of the phenomena exhibited by photons.
4. The speed of a photon depends on the medium through which it propagates.
