Understanding the Photoelectric Effect by toeghfa is a document available to read on EtoBox.
The photoelectric effect describes the ejection of electrons from a metal surface when exposed to electromagnetic radiation of suitable frequency, first observed by Heinrich Hertz and explained by Albert Einstein. It demonstrates that light has a particle nature, as the wave theory could not account for phenomena such as the threshold frequency and the dependence of ejected electron energy on light frequency. This effect led to the development of quantum theory, highlighting the dual nature of light as both
