In photoelectric effect, the electrons are ejected from metals if the incident light has a certain minimum.
The photoelectric emission from a surface starts only when the light incident upon the surface has certain minimum:
A certain element 'A' undergoes photoelectric emission when bombarded by one photon of indigo light. When the material containing the same element was bombarded by two photons of red light with a total of same energy as that of indigo photon, no electron was emitted. Explain.
Does the stopping potential in photoelectric emission depend upon the intensity of the incident radiation in a photo cell? Comment on it.
Derive de Broglie wave equation for material particles. (b) Why does photoelectric emission not take place if the frequency of incident radiation is less than threshold frequency ?
In a photoelectric experiment increasing the intensity of incident light
