This phenomenon is known as the photoelectric effect. As well as …
Webb25 jan. 2008 · Answer: The photoelectric effect is a phenomenon in which electrons are emitted from the surface of matter (usually metals) when light shines upon it. Einstein explained the effect by proposing that light consists of small particles, or quanta, called photons, which carry energy that is proportional to the frequency of light.
