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 ...

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 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 ...

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” ...

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 ...

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 ...

When Einstein was awarded the Nobel Prize in Physics in 1921, he was immediately thrown in to the spotlight of the scientific world, and which has stayed on him for nearly 100 years. He won it for his ...

Albert Einstein received the 1921 Nobel Prize in Physics for his contributions to theoretical physics and his discovery of ...

Solar panels use a scientific concept called the photovoltaic effect to turn sunlight into electricity. Here's a deep dive into how it all works. You've probably wondered what kind of magic in solar ...

The photoelectric effect is the emission of electrons from matter upon the absorption of electromagnetic radiation, such as ultraviolet radiation or x-rays. Upon exposing a metallic surface to ...

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

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 ...
