photoelectric effect In physics, the emission of electrons from a substance (usually a metallic surface) when it is struck by photons (quanta of electromagnetic radiation), usually those of visible light or ultraviolet radiation. The energy of the emitted electrons depends on the frequency of the incident radiation (which must exceed a characteristic threshold frequency); the higher the frequency, the greater the energy of its photons. The number of electrons emitted depends on the radiation's intensity (rate of transfer of energy per unit area). The effect was first observed 1887 by Heinrich Hertz (better known for his researches on electromagnetic waves), who showed that electric sparks occur more easily when the electrodes are illuminated with ultraviolet light (see ultraviolet radiation ). It was established in 1900 as being due to the ejection of electrons by the light. This discovery, along with the identification of the beta particles observed in radioactivity as being electrons also, helped establish the fundamental nature of electrons as a constituent of all atoms. The theory of the photoelectric effect, a quantum theory of radiation, was formulated by Albert Einstein 1905.

Technology Philipp Lenard Scientist: Philipp Eduard Anton Lenard Home Library Science Dictionary of Scientists German physicist (1862–1947) Born the son of a wine merchant in Pozsony (now Bratislava in Slovakia), Lenard studied at the universities of Budapest, Vienna, Berlin, and Heidelberg , where he obtained his doctorate. He taught at the universities of Bonn (1893), Breslau (1894), Aachen (1895), and Heidelberg (1896). In 1898 he was appointed professor of experimental physics at Kiel. He returned to Heidelberg in 1907, where he remained until his retirement in 1931. Lenard 's career falls naturally into two distinct periods. Before 1914 he made several major contributions to fundamental physics. In particular he investigated the photoelectric effect . It had been known for some time that light falling on certain metals would cause the emission of electrons. Starting in 1899 Lenard investigated why the effect could only be produced by ultraviolet or shortwave light. In the course of his experiments he established two

Lenard, Philipp Eduard Anton Hungarian-born German physicist who investigated the photoelectric effect and cathode rays (the stream of electrons emitted from the cathode in a vacuum tube). Nobel prize 1905. Lenard was born in Pozsony, Hungary (now Bratislava, Slovak Republic), and studied at Heidelberg and Berlin. In 1898 he became professor of experimental physics at Kiel, and held the same post at Heidelberg 1907-31. In 1924 Lenard became a Nazi. Obsessed with the idea of producing a purely 'Aryan' physics, he spent his later years reviling Albert Einstein and other Jewish physicists. Lenard's work on cathode rays began 1892, and led him to the conclusion that an atom is mostly empty space. He also suggested that the part of the atom where the mass was concentrated consisted of neutral doublets or 'dynamids' of negative and positive electricity. This preceded by ten years the classic model of the atom proposed by Ernest Rutherford Lenard devised the grid in the thermionic valve that controls electron flow. He showed that an electron must have a certain minimum energy before it can produce ionization in a gas. He also studied luminescent compounds and, from 1902 onwards, discovered several fundamental effects in photoelectricity.
