However, with wavelengths of only 13 nanometers and high radiation intensities of several petawatt per square centimeter something else – at least with some atoms – happens: With xenon, a whole ...

When light hits a material, electrons can be released from this material -- the photoelectric effect. Although this effect played a major role in the development of the quantum theory, it still holds ...

In a flash: artist's impression of the photoelectric effect. (Courtesy: Technical University of Vienna) Just 45 quintillionth of a second (45 attoseconds) is all it takes for a photon to liberate an ...

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 ...

The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Electrons emitted in this manner are called photoelectrons. The phenomenon is ...

FRANKFURT. It is now exactly one hundred years ago that Albert Einstein was awarded the Nobel Prize in Physics for his work on the photoelectric effect. The jury had not yet really understood his ...
