The photoelectric effect refers to what happens when electrons are emitted from a material that has absorbed electromagnetic radiation. Physicist Albert Einstein was the first to describe the ...

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, ...

The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When ...

Although the photoelectric effect in molecules has been studied extensively in the meantime, it has not yet been possible to determine its evolution over time in an experimental measurement.

Despite the popularity of Einstein's theories of relativity and his musings on black holes, Einstein's Nobel Prize in physics was actually awarded for his discovery of the photoelectric effect.

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 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 ...

As the photoelectric effect occurs so fast, physicists used to think the emission time is too short for them to measure with any precision. But thanks to the development of shorter and shorter laser ...

Einstein's description of the photoelectric effect, also known as photoionization, laid the theoretical foundation for quantum mechanics. However, the instantaneous nature of this effect has been ...

[Ashish] demonstrates the well-known photoelectric effect by triggering a sub-biased neon lamp with visible light from an LED. Neon bulbs work on the principle of voltage-induced ionization, ...

But while there is still no quantum theory of gravity, the challenge of detecting its signatures now looks a little more manageable thanks to a proposed experiment that takes inspiration from the ...

The idea that Einstein described in 1905—that won the Nobel Prize a decade and half later—is what makes today's solar panels work at all. But it wasn't until 1954—almost 50 years later ...
