Science > Physics > Photoelectric Effect > Photoelectric Effect. It is found that when the light of very short wavelength (or high frequency) is incident on a certain metallic surface of photosensitive material, electrons are emitted by the surface. Most of the metals emit electrons when ultra-violet light is incident on them.

The photoelectric effect is an important concept that enables us to clearly understand the quantum nature of light and electrons. The photoelectric effect is a phenomenon in physics. The effect is based on the idea that electromagnetic radiation is made of a series of particles called photons. When a photon hits an electron on a metal surface, the electron can be emitted. The emitted electrons are called photoelectrons. Devices based on the photoelectric effect have several desirable properties, including producing a current that is directly proportional to light intensity and a very fast response time. One basic device is the photoelectric cell, or photodiode.

The photoelectric effect refers to the emission, or ejection, of electrons from the surface of, generally, a metal in response to incident light. Energy contained within the incident light is absorbed by electrons within the metal, giving the electrons sufficient energy to be 'knocked' out of, that is, emitted from, the surface of the metal.

2008-03-17 · The photoelectric effect is a quantum-mechanical phenomenon in which light impinging on the surface of a metal can cause electrons to be ejected. Only light with wavelengths shorter than some threshold value , characteristic of each metal, can cause emission of photoelectrons, no matter how intense the radiation.

In 1905 Albert Einstein (1879–1955) proposed that light be described as quanta of energy that behave as particles. A photon is a particle of electromagnetic radiation that has zero mass and carries a quantum of energy. Einstein's Legacy: The Photoelectric Effect. Despite the popularity of Einstein's theories of relativity and his musings on black holes, Einstein's Nobel Prize in physics was actually awarded for According to the Photoelectric effect, when a metal surface is irradiated with light of sufficient energy, it causes the electrons of the metal to eject out.
