* emisssion of electron from the surface of the metal when light of suitable frequency falls-photoelectric emission.
* emision of electron from the metal by quantum tunnling of electron.
No, the reverse process of the photoelectric effect is not the Zeeman effect. The Zeeman effect is the splitting of spectral lines in the presence of a magnetic field, while the photoelectric effect is the emission of electrons from a material when exposed to light. They are two distinct phenomena in physics.
Electrons are produced by various processes, including photoelectric effect, thermal emission, field emission, and radioactive decay. In materials, electrons can also be generated by chemical reactions or through the application of electric fields.
Field emission can result in the emission of electrons from a material's surface when a strong electric field is applied, leading to current flow in a vacuum or low-pressure environment. This phenomenon is used in technologies like field emission displays and electron microscopy. It can also lead to material degradation due to the loss of surface atoms during emission.
The electric field between two plates is directly proportional to the potential difference across them. This relationship is described by the equation E V/d, where E is the electric field, V is the potential difference, and d is the distance between the plates.
The electric field between two plates can be calculated by dividing the voltage difference between the plates by the distance separating them. This formula is represented as E V/d, where E is the electric field strength, V is the voltage difference, and d is the distance between the plates.

no there is not my question
I do track and field
