WebThe photoemission or photoelectric effect is a quantum electronic phenomenon in which electrons (photoelectrons) are emitted from matter after the absorption of energy from electromagnetic radiation such as UV light or X-ray.. When UV light or X-ray is absorbed by matter, electrons are excited from core levels into unoccupied states, leaving empty core … WebWave-Particle Duality. Publicized early in the debate about whether light was composed of particles or waves, a wave-particle dual nature soon was found to be characteristic of electrons as well. The evidence for the description of light as waves was well established at the turn of the century when the photoelectric effect introduced firm ...

WebIII.A.1 The Photoelectric Effect.
