The photoelectric effect is the emission of electrons or other free carriers when light is shone onto a material electrons emitted in this manner can be called photo electrons the phenomenon is commonly studied in electronic physics, as well as in fields of chemistry, such as quantum chemistry or electrochemistry. Definition of photoelectric in the audioenglishorg dictionary meaning of photoelectric what does photoelectric mean proper usage and pronunciation (in phonetic transcription) of the word photoelectric. 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. Photoelectric effect if suitable light is allowed to fall on plate 'p', it will give out photo electrons as shown in the figure the photo electrons are attracted by the collector 'c' connected to the +ve terminal of a battery. Photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation the effect is often defined as the ejection of electrons from a metal plate when light falls on it.
How do photovoltaics work some materials exhibit a property known as the photoelectric effect that causes them to absorb photons of light and release electrons. Define the photoelectric effect the photoelectric effect synonyms, the photoelectric effect pronunciation, the photoelectric effect translation, english dictionary definition of the photoelectric effect. Looking for online definition of the photoelectric effect in the medical dictionary the photoelectric effect explanation free what is the photoelectric effect. The photoelectric effect is also employed in photocells such as can be found in solar panels and this is frequently used to make electricity commercially.
The photoelectric effect will not occur when the frequency of the incident light is less than the threshold frequency different materials have different threshold frequencies most elements have threshold frequencies in the ultraviolet region of. Ejection of electrons from an atom or molecule that has absorbed a photon of sufficient energy the photoelectric effect is the operating principle behind electric eyes it is experimental evidence for particle-like behavior of electromagnetic radiation.

The effect has a number of practical applications, most based on the photoelectric cell photoelectric cell or photocell, device whose electrical characteristics (eg, current, voltage, or resistance) vary when light is incident upon it. Define the photoelectric effect when one photon of high enough energy is absorbed by one electron and released from the metal surface what is the definition of.
At small values of gamma ray energy the photoelectric effect dominates the cross-section curve have sharp discontinuities cross-section of photoelectric effect. How can the answer be improved. The photoelectric effect occurs when light above a certain frequency (the threshold frequency) is shone on metals like zinc, this causes electrons to escape from the. Looking for online definition of photoelectric in the medical dictionary photoelectric explanation free what is photoelectric meaning of photoelectric medical term.
Photoelectric effect the photoelectric effect occurs when light above a certain frequency (the threshold frequency) is shone on metals like zinc, this causes electrons to. Photoelectric effect the phenomenon in which the absorption of electromagnetic radiation, as light, of sufficiently high frequency by a surface, usually metallic, induces the emission of electrons from the surface. Photoelectric effect when light hits a metal surface it can produce an electric potential this phenomenon is called photoelectric effect this concept is used to generate electricity directly from the energy of light.
Photoelectric effect: photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation. Definitions of photoelectric_effect, synonyms, antonyms, derivatives of photoelectric_effect, analogical dictionary of photoelectric_effect (english. Definition of photoelectric - characterized by or involving the emission of electrons from a surface by the action of light. Throughout the 1960s and 1970s, the company modernized its line of fire alarm products with modular control panels, ionization and photoelectric smoke detectors, and compact audible and visible signaling appliances. When light of suitable frequency falls on a metal surface, electrons are emitted from the metal surfacethis phenomenon is called photoelectric effect.
H is planck's constant ν is the frequency of the incident photon w is the work function, which is the minimum energy required to remove an electron from the surface of a given metal: hν0 e is the maximum kinetic energy of ejected electrons: 1/2 mv2 ν0 is the threshold frequency for the photoelectric effect. Define photoelectric photoelectric synonyms, photoelectric pronunciation, photoelectric translation, english dictionary definition of photoelectric also pho o ec ri al adj. In other words photoelectric effect is a phenomenon in which, when the light(photon) of appropriate wavelength or frequency incidents on the metallic surface called photo cathode, then due to the production of photo electrons, photocurrent is generated. Discussion dilemma under the right circumstances light can be used to push electrons, freeing them from the surface of a solid this process is called the photoelectric effect (or photoelectric emission or photoemission), a material that can exhibit this phenomena is said to be photoemissive, and the ejected electrons are called photoelectrons.
