Pert
1 Pertaining to the photoelectric effect
Pertaining to the electrical effects of light or other radiation; for example, emissions of electrons
A substance is photoelectric if it ejects electrons when light strikes it
Acting by the operation of both light and electricity; said of apparatus for producing pictures by electric light
of or pertaining to photoelectricity; "the photoelectric effect"
Involves a small lamp adjusted to direct a narrow light beam across the detection chamber Next to this light source, but hidden from direct exposure to the beam, is a light-sensitive photocell Smoke entering the detection chamber scatters the light beam reflecting it in all directions Some of this reflected light is picked up by the photocell which, at a preset level, triggers the alarm
pertaining to the conversion of light (radiant energy) to electricity
of or pertaining to photoelectricity; "the photoelectric effect
photoelectric cell
A transducer that generates an electric current proportional to the light intensity
photoelectric effect
The emission of electrons from the surface of a material following the absorption of electromagnetic radiation
photoelectric cell
An electronic device having an electrical output that varies in response to incident radiation, especially to visible light. Also called electric eye
photoelectric cell
a transducer used to detect and measure light and other radiations
photoelectric cell
A cell (as one of two electrodes embedded in selenium) which by exposure to light generates an electric current
photoelectric effect
transfer of energy from light rays that touch the electrons in a substance
photoelectric effect
Ejection of electrons from a substance by incident electromagnetic radiation, especially by visible light. Phenomenon in which charged particles are released from a material when it absorbs radiant energy (see radiation). It is often thought of as the ejection of electrons from the surface of a metal plate when visible light falls on it. It can also occur if the radiation is in the wavelength range of ultraviolet radiation, X rays, or gamma rays. The emitting surface may be a solid, liquid, or gas, and the emitted particles may be electrons or ions. The effect was discovered in 1887 by Heinrich Hertz and explained by Albert Einstein in work for which he received the Nobel Prize
photoelectric emission
the release or absorption of quanta above a certain energy level
photoelectrically
By means of photoelectricity
photoelectrically
in a photoelectrical manner, by emission of electrons from metals under electromagnetic radiation
photoelectrically
by photoelectric means; "they measured it photoelectrically
