The maximum kinetic energy of the photo electron is

A photosensitive plate is illuminated by green light and photoelectrons are emitted with maximum kinetic energy equal to 4 eV. If the intensity of the radiations is reduced to one fourth of its original value, then the maximum kinetic energy of the photo electrons will be :

If light of wavelength of maximum intensity emitted from surface at temperature T_(1) Is used to cause photoelectric emission from a metallic surface, the maximum kinetic energy of the emitted electron is 6 ev, which is 3 time the work function of the metallic surface. If light of wavelength of maximum intensity emitted from a surface at temperature T_(2) (T_(2)=2T_(1)) is used, the maximum kinetic energy of the photo electrons emitted is
