The method of image charges (also known as the method of images and method of mirror charges) is a basic problem-solving tool in electrostatics.The name originates from the replacement of certain elements in the original layout with fictitious charges, which replicates the boundary conditions of the problem (see Dirichlet boundary conditions or Neumann boundary conditions).
The tube was evacuated to different amounts and a series of images recorded. At the lowest pressure the image of the open slit was clear, while images of the mica covered slit or the open slit at higher pressures was fuzzy. Rutherford explained these results as alpha-particle scattering [7]: 260 in a paper published in 1906. [28]
Ernest Rutherford. Ernest Rutherford, 1st Baron Rutherford of Nelson, OM FRS HonFRSE [7] (30 August 1871 – 19 October 1937) was a New Zealand physicist who was a pioneering researcher in both atomic and nuclear physics. Rutherford has been described as "the father of nuclear physics", [8] and "the greatest experimentalist since Michael ...
J. J. Thomson. Sir Joseph John Thomson OM FRS [ 1] (18 December 1856 – 30 August 1940) was a British physicist and Nobel Laureate in Physics, credited with the discovery of the electron, the first subatomic particle to be found. In 1897, Thomson showed that cathode rays were composed of previously unknown negatively charged particles (now ...
In modern physics, the double-slit experiment demonstrates that light and matter can satisfy the seemingly incongruous classical definitions for both waves and particles. This ambiguity is considered evidence for the fundamentally probabilistic nature of quantum mechanics. This type of experiment was first performed by Thomas Young in 1801, as ...
Photoelectric effect. Photoemission of electrons from a metal plate accompanied by the absorption of light quanta – photons. The photoelectric effect is the emission of electrons from a material caused by electromagnetic radiation such as ultraviolet light. Electrons emitted in this manner are called photoelectrons.
Wu experiment. Chien-Shiung Wu, after whom the Wu experiment is named, designed the experiment and led the team that carried out the test of the conservation of parity in 1956. The Wu experiment was a particle and nuclear physics experiment conducted in 1956 by the Chinese American physicist Chien-Shiung Wu in collaboration with the Low ...
An opposite charge is induced on the inside surface of the pail. Faraday's ice pail experiment is a simple electrostatics experiment performed in 1843 by British scientist Michael Faraday [1] [2] that demonstrates the effect of electrostatic induction on a conducting container. For a container, Faraday used a metal pail made to hold ice, which ...
