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 ...

According to quantum mechanics, our universe is like a Lego set. All matter particles, as well as particles such as light that act as messengers between them, come in discrete blocks of energy. By ...

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 ...

Photoelectric detection systems form an essential cornerstone of modern optical instrumentation. These systems capitalise on the photoelectric effect to convert incident light into electrical signals, ...
