hi pf, while reading photoelectric effect i found that one photon of light causes the emission of one electron? I want to know why?
dev70 said:as far as i know or i searched in the web i found in many sites saying that one electron can absorb the energy of one photon or somewhat similar to what i asked. i want to know how and why?

will there be emission of electrons if the energy of incident wave is exactly equal to work function?
A photon is a fundamental particle that makes up light. When a photon comes into contact with an atom, it can transfer its energy to an electron in the atom. This energy causes the electron to become excited and move to a higher energy level, resulting in the emission of the electron.
The energy of a photon is directly related to its frequency. Each electron in an atom has a specific energy level, and only a photon with the exact energy level can cause the electron to move. Therefore, only one photon with the right energy level can cause the emission of one electron.
Yes, it is possible for multiple photons to cause the emission of one electron. This is known as multi-photon ionization and occurs when a high-intensity laser is used to bombard an atom with multiple photons, providing enough combined energy to excite the electron.
The energy of the photon, the energy level of the electron, and the angle at which the photon hits the atom can all influence the emission of an electron. Additionally, the type of material the photon interacts with can also affect the process.
No, the emission of an electron by a photon is a predictable and consistent process. The energy levels of electrons and the energy of photons are well understood, allowing scientists to accurately predict when and how the emission of an electron will occur.
