Photons are electromagnetic radiation with zero mass, zero charge, and a velocity that is always c, the speed of light. These electrons will ultimately deposit their energy in the medium. Photons Scattering of radiation from an electron (Compton effect). Compton effect provides a direct confirmation of particle nature of radiation. Why photoelectric effect cannot be exhited by a free electron. “.

If Eve eavesdrops on some of them, they may randomly change their direction of polarisation. ATS 150. Lecture 5. Please read Chapter 4 . in Archer Textbook. Gases.
