Results of photoelectric effect:

a) Energy of the emitted electrons is independent of the intensity of radiation

b) There exists a threshold frequency of the incident energy, below which no electrons are emitted, no matter how intense the beam of radiation is. If the frequency of radiation is greater than the threshold frequency, the extra energy seems to increase the energy of emitted electrons.

c) No time lag between the irradiation and production of emitted electrons

d) Number of the emitted electrons is proportional to the intensity of radiation falling on the metal surface. Maximum energy of the emitted electrons for a fixed incident energy of one frequency, is the same.

e) Different metals have different threshold frequencies.
