In 1905, Albert Einstein showed that the photoelectric effect—the ability of metals to produce an electric current when exposed to light—could be explained if light is quantum, traveling in discrete ...
The photoelectric effect is a phenomenon where light knocks electrons out of a material, resulting in the emission of these electrons, called photoelectrons. Albert Einstein explained the ...
X-ray backscatter AIT uses a narrow beam of X-ray photons with energies, hv, less than 100 keV. 2 There are five basic interactions that can occur as X rays penetrate material. These are the ...
