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 ...

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 ...

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 ...

June 9, 2022, marks 117 years since Einstein published his groundbreaking paper on the photoelectric principle. The analysis was published on June 9, 1905, also known as Einstein’s “miracle year” ...

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 ...

Who is Einstein? This video explores the life and contributions of Albert Einstein, the renowned physicist known for ...

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 ...

In the photoelectric effect, a photon ejects an electron from a material. Researchers have now used attosecond laser pulses to measure the time evolution of this effect in molecules. From their ...

Super-intense lasers can boot bunches of electrons from the inner region of atoms, according to a new study. This extension of the photoelectric effect, in which one photon knocks one electron off the ...

THE sugar industry is becoming increasingly interested in the possibility of replacing polarimeters of the visual type with photoelectric instruments. Of the various designs which have been suggested, ...
