Laws of Photoelectric Emission…

Laws of Photoelectric Emission – The following are the laws of photoelectric emission:
(i) Photoelectric emission is a one-time event.
(ii) Photoelectric current (or photoelectrons expelled per second) is proportional to incident light intensity.
(iii) The velocity of released electrons is unaffected by light intensity and is solely determined by the frequency (or wavelength) of the incident light.
(iv) There is a minimum frequency below which the emission of electrons stops completely for a specific metal. The threshold frequency is the frequency at which something happens.
