Q. State any three laws of photo electric emission?
(i) For a specified photo sensitive material there is a minimum frequency called the threshold frequency below which emission of photoelectrons stops completely however great the intensity may be.
(ii) For a specified photosensitive material the photo electric current is directly proportional to the intensity of the incident radiation provided the frequency is greater than the threshold frequency.
(iii) The photoelectric release is an instantaneous process that is there is no time lag between the incidence of radiation and the emission of photo electrons.
(iv) The maximum kinetic energy of the photo electrons is straight proportional to the frequency of incident radiation, but is independent of its intensity.
