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 ...

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 ...

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 ...

When a photon hits a material, it can eject an electron from it provided it has enough energy. Albert Einstein found the theoretical explanation of this phenomenon, which is known as the photoelectric ...

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 ...

Scientific American presents Everyday Einstein by Quick & Dirty Tips. Scientific American and Quick & Dirty Tips are both Macmillan companies. When you think of Albert Einstein, what do you think of?

For his monumental work in transforming our understanding of gravity and spacetime, Albert Einstein won his sole Nobel Prize for something else: explaining the photoelectric effect. In the early 20th ...

IN a letter dated April 26 which appeared in NATURE of May 12, Mr. Stuhlmann, of Princeton University, U.S.A., describes some experiments which he has carried out on the photoelectric effect of ...

Albert Einstein never won a Nobel prize for the theory of relativity—in fact, it was only through long, political jockeying within the Nobel committee that he won the prize at all. Instead, when he ...

I took a deep dive into the photoelectric effect — where light hits a surface and kicks electrons out. It’s simple, mind-blowing, and totally changed how we understand energy and matter. Here’s how it ...
