Light is everywhere,it illuminates our world, enables vision, and travels across galaxies. But what is light, really? Is it a ...

Gravity, a crucial piece of the universe, is missing from the quantum Lego set. But while there is still no quantum theory of gravity, the challenge of detecting its signatures now looks a little more ...

The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When high-energy light hits atoms, it knocks electrons loose. This process ...

Experiments on the photoelectric effect where electrons are generated as light strikes a metal contradicted Maxwell's theory on light ... diodes which exclusively rely on the principles of quantum ...

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 ...

The electrons emitted during the photoelectric effect contain a lot of information about the irradiated material.By measuring the quantum state of the photoelectron, our technique can precisely ...

In the past, chemists have used temperature, pressure, light, and other chemical ways to speed up or slow down chemical ...

Blasting the photoelectric effect out of the quantum realm with a very intense light source Einstein showed how the photoelectric effect argued for a quantum view of … ...

In this period (1913–1923), there was simply no convincing explanation of the photoelectric effect. At its end, light quantum was reluctantly accepted to relieve what had become an intolerable ...

Einstein showed how the photoelectric effect argued for a quantum view of light. Some researchers have now shown that, with a sufficiently intense light source, it's possible to get photoelectric ...

The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When high-energy light hits atoms, it knocks electrons loose.
