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 incident radiation, we can calculate the energy of the electrons in the solid metal. WebToday, the photoelectric effect has many practical applications as well. From medical imaging to the production of clean energy, the discovery and application of this effect now has implications that go well beyond simply understanding the science.
