Web20 feb. 2024 · The maximum kinetic energy K E e of ejected electrons (photoelectrons) is given by K E e = h f − B E, where h f is the photon energy and BE is the binding energy (or work function) of the electron to the particular material. Glossary photoelectric effect … WebThe photoelectric effect is as follows: when electrons in a metal are exposed to light of sufficient radiation, the electrons are ejected from the metal surface. If we know the kinetic energy of the ejected electrons (known as photoelectrons) and the energy of the …

Web5 dec. 2024 · Stopping potential, Photoelectric work function, maximum kinetic energy – Light of wavelength 2024 Å is incident on the cathode of a photocell. The current in the photocell is reduced to zero by stopping potential of 2 V. Find the. Web1 Answer Sorted by: 1 You're not doing this wrong. As you know energy of each photon is E = h f = 2.27 e V so they can't produce any photoelectrons on a metal with work function greater than that.

These results were completely at odds with the predictions based on the classical description of light as a wave! In order to explain what was happening, it turned out that an entirely new … So, from that we're going to subtract the work function 3.43 times 10 to the … The detector detects the energy absorbed.
