It can also occur if the radiation is in the wavelength range of ultraviolet radiation, X rays, or gamma rays. This study discusses the effectiveness of the hot model, which is proposed by Kuralin the conceptual change of the students for the photoelectric effect.

Although hot factors, such as motivation, are added up to the conceptual change models cumulatively in time, Kuralwho asserts that teaching models based on the conceptual change mostly depend on cold conceptual change, suggests a teaching model based on cognitive conflict which is back up by motivational and metacognitive strategies for hot conceptual change.

Also called electric eye 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.


The effect was discovered in 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 in a photoelectrical manner, by emission of electrons from metals under electromagnetic radiation photoelectrically By means of photoelectricity photoelectrically by photoelectric means; “they measured it photoelectrically.

The emitting surface may be a solid, liquid, or gas, and the emitted particles may be electrons or ions.
