The photoelectric effect is the emission of electrons or other free carriers when light shines on a material. Electrons emitted in this manner can be called photo electrons. ... According to classical electromagnetic theory, this effect can be attributed to the transfer of energy from the light to an electron.

(a) Photoelectric effect is an instantaneous process.
(b) Photoelectric current is directly proportional to the intensity of incident light and is independent of frequency.
(c) The stopping potential and hence the maximum velocity of the electrons depends upon the frequency of incident light and is independent of its intensity.
(d) The emission of electrons stops below a certain minimum frequency known as threshold frequency.
