Section B experiments: To demonstrate thermionic emission and deflection of cathode rays in EM fields To demonstrate the photoelectric effect To demonstrate a photocell
Formulae: Photon energy: E = hf
STS: cathode ray tube/monitors, X-ray production and use photoelectric application and photocells Scientists: Stoney, Röntgen, Hertz, Hallwachs, Planck, Einstein, Thompson and Millikan Laws: Einstein’s photoelectric law
Work function: f = hf0 Einstein’s photoelectric law: hf = f + 1 __ 2
