As the intensity of incident light increases
Photoelectric current increases
Photoelectric current decreases
Kinetic energy of emitted photoelectrons increases
Kinetic energy of emitted photoelectrons decreases
Intensity increases means more photons of same energy will emit more electrons of same energy, hence only photoelectric current increases.
Work function of metal A is equal to the ionization energy of hydrogen atom in the first excited state. Work function of metal B is equal to the ionization energy of He+ ion in the second orbit. Photons of same energy E are incident on both A and B. Maximum kinetic energy of photoelectrons emitted from A is twice that of photoelectron emitted from B. The difference in maximum kinetic energy of photoelectrons from A and from B.
