Photoelectric effect - The photoelectric effect is the emission of electrons from matter upon the absorption of electromagnetic radiation, such as ultraviolet radiation or x-rays. An older term for the photoelectric effect was the Hertz effect, though this phrase has fallen out of current use.
Corpuscular theory - The Corpuscular theory, set forward by Isaac Newton states that light is made up of small discrete particles called corpuscles. This theory, related to the theory of Photons, explains many properties of light such as photoelectric effect.
Densitometer - Densitometer is a device that measures the degree of darkness in photographic or semitransparent material. The densitometer is basically a light source aimed at a photoelectric cell which determines the density of the sample from differences in the readings.
Photocells - A photocell is a device that uses the photoelectric effect to convert energy from sunlight into electrical energy. These devices include photovoltaic, or solar cells.
