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 ...

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

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

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 ...

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

Wave particle duality The photoelectric effect shows that light is made up of individual photons. Photoemissions will take place if photons have a high enough frequency and have enough energy.

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 ...
