Topic: Photoelectric Effect
This topic describes the emission of electrons from a metal surface when light of high enough frequency strikes it. It confirms that light behaves as particles known as photons. The photoelectric effect is determined by the frequency of light rather than its intensity. A minimum threshold frequency is necessary for electrons to be emitted from the metal. This phenomenon contributed significantly to the rise of quantum theory and was clearly explained by Einstein.
