In order to increase the kinetic energy of ejected photoelectrons, there should be an increase in

The maximum kinetic energy of photoelectrons

Number of ejected photoelectron increases with increase

Number of ejected photoelectrons increases with increases

When the energy of the incident radiation is increased by 20%, the kinetic energy of the photoelectrons emitted from a metal surface increased from 0.5eV to 0.8eV. The work function of the metal is

When the energy of the incident radiation is increased by 20%, the kinetic energy of the photoelectrons emitted from a metal surface increased from 0.5 eV to 0.8 eV. The work function of the metal is:

Photoelectrons are being obtained by irradiating zinc by a radiation of BlOO A. In order to increase the kinetic energy of ejected photoelectrons:
