the emission of electrons in a material when a material is illuminated with electromagnetic radiation

The photoelectric effect is the emission of electrons in a material when a material is illuminated with electromagnetic radiation (visible or ultraviolet light in general).

the emission of electrons by substances

: The Photoelectric Effect describes the emission of electrons by substances when light falls on their surface.

the emission of electrons from some solids when struck by light

In a single stroke Johann Ambrosius Barth thus revolutionized the theory of light and provided an explanation for, among other phenomena, the emission of electrons from some solids when struck by light, called the photoelectric effect' (Britannica).

to the occurrence in which electrons are discharged from the surface of a metal when light strikes a metal

The Photoelectric Effect, as described by Einstein, refers to the occurrence in which electrons are discharged from the surface of a metal when light strikes a metal .

a phenomenon in which electrons are emitted from matter after the absorption of energy from electromagnetic radiation such as X-rays or visible light

The photoelectric effect is a phenomenon in which electrons are emitted from matter after the absorption of energy from electromagnetic radiation such as X-rays or visible light.

the process in which EM radiation ejects electrons from a material

The photoelectric effect is the process in which EM radiation ejects electrons from a material.

to the emission of electrons

Discovered by Albert Einstein in 1905 and later confirmed through experiments conducted by Philipp Lenard, the Photoelectric Effect refers to the emission of electrons when light is shone on a material surface.

the dominant energy transfer mechanism for X-ray and gamma ray photons with energies below 50 keV (thousand electronvolts)

The photoelectric effect is the dominant energy transfer mechanism for X-ray and gamma ray photons with energies below 50 keV (thousand electronvolts), but thousand electronvolts is much less important at higher energies.

the emission of electrons from the surface of a metal due to exposure of electromagnetic radiation above a certain frequency

The photoelectric effect is the emission of electrons from the surface of a metal due to exposure of electromagnetic radiation above a certain frequency.

the phenomenon of electrons being released from a given metal

The photoelectric effect is the phenomenon of electrons being released from a given metal when the given metal is exposed to light.

a phenomenon known as the photoelectric effect, a process which allows the materials to absorb light photons and subsequently release electrons

Photovoltaic materials produce a phenomenon known as the photoelectric effect, a process which allows the materials to absorb light photons and subsequently release electrons.
