NECO Physics 2023 Answers Essay
Photo-electrons are particles of light, or photons, that are emitted when a photon of sufficient energy strikes a material. They are the result of the photoelectric effect, which is the emission of electrons from a material when it is exposed to electromagnetic radiation. Photo-electrons are typically used in photoelectric detectors, which are used to measure the intensity of light.
Threshold frequency = (Work function x 1.6×10^-19 J) / (h x 66×10^-34 Js)
Threshold frequency = (3.5eV x 1.6×10^-19 J) / (66×10^-34 Js)
Threshold frequency = 2.27×10^14 Hz
Pick any two(2)
