The relationship between energy and frequency, and the independence of these values from amplitude, is shown in the table below.

WebbObserving the Photoelectric Effect The photoelectric effect can be observed on a gold leaf electroscope; A plate of metal, usually zinc, is attached to a gold leaf, which initially has a negative charge, causing it to be repelled by a central negatively charged rod; This causes negative charge, or electrons, to build up on the zinc plate WebbThe photoelectric effect is an experiment in which light is incident on a metal and as a result electrons are emitted. In the photoelectric effect light can be seen as being …

Webb21 juni 2024 · The photoelectric effect is one of the basic pylons of the need to introduce quantum mechanics. (An other is the black body radiation). The data can be interpreted only as a particulate nature of light, one photon kicking out one electron, and the electron is bound with a minimum energy.
