WebbThe photoelectric effect proves that energy is quantised. These lumps or packets of energy are called photons. This contradicts the long accepted wave model, where light is considered as an electromagnetic wave, with energy arriving continuously. The photon model was Einstein’s explanation of the photoelectric effect. How did they prove that … WebbEinstein's explanation of the photoelectric effect: Einstein provided an explanation for the photoelectric effect by postulating the existence of photons, quanta of light energy with …

WebbQuestion: 2. The photoelectric effect shows that a minimum amount of energy is needed to eject an electron from a piece of metal. This supports the idea of quantized energy because it shows that changes in the intensity of the light have an effect on the ejection of electrons from a metal. WebbWhat's the photoelectric effect? It's been determined experimentally that when light shines on a metal surface, the surface emits electrons. For example, you can start a current in a …
