Here’s a fun video by [Ashish Derhgawen], discussing the photoelectric effect of neon lamps with some simple demonstrations. Orange light makes it light! [Ashish] demonstrates the well-known ...

Albert Einstein shook up physics by proposing that light wasn’t just a wave, but it could also behave like a collection of ...

Physicists have uncovered a new quantum phenomenon, proving for the first time that electrons can form vortex-like structures ...

Light was long considered to be a wave, exhibiting the phenomenon of interference in which ripples like those in water waves ...

In this interview, Busto discusses the findings. The photoelectric effect was explained over a century ago by Einstein, laying the foundations for the development of quantum mechanics. This same ...

Researchers have experimentally demonstrated a quantum tornado. Electrons form vortices in the momentum space of the quantum semi-metal tantalum arsenide.

Scientists experimentally confirm electron vortices in momentum space, a quantum phenomenon that could enable efficient, ...

Albert Einstein won the 1921 Nobel Prize in Physics “for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect” but is best known for his ...

XPS relies on the photoelectric effect, where irradiating a material with X-rays causes the emission of core electrons. The kinetic energy of these emitted electrons is measured, which can be directly ...
