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 ...

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 ...
