WebFeb 2, 2024 · The photoelectric effect should occur for any light, regardless of frequency or wavelength. There should be a delay on the order of seconds between the radiation’s contact with the metal and the initial release of photoelectrons. The Experimental Result WebThe photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material.Electrons emitted in this manner are called photoelectrons. The phenomenon is studied in condensed matter physics, and solid state and quantum chemistry to draw inferences about the properties of atoms, molecules and solids. The …

Webequations. Einstein and Millikan described the photoelectric effect using a formula (in contemporary notation) that relates the maximum kinetic energy ( Kmax) of the photoelectrons to the frequency of the absorbed photons ( f) and the threshold frequency ( f0) of the photoemissive surface. Kmax = h ( f − f0)
WebSep 20, 2024 · The photoelectric effectis a phenomenon that occurs when light shone onto a metal surface causes the ejection of electrons from that metal. It was observed that only certain frequencies of light are able to cause the ejection of electrons. can flaxseed lower blood sugarWebThe photoelectric effect shows that light is made up of individual photons.
