Neon lamps are fun to play with. These old-school indicators were once heavily utilized in many types of equipment for indication purposes but now seem largely relegated to mains voltage ...

A team of scientists from the Department of Energy's SLAC National Accelerator Laboratory has uncovered new information about ...

Millikan's experiments did not bring about the acceptance of light quanta. In this period (1913–1923), there was simply no convincing explanation of the photoelectric effect.

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 ...
