The work function of a metal is 3.4 eV. If the frequency of incident radiation is increased to twice, then the work function of the metal becomes.

Does work function depend on the frequency of incident radiation?

The maximum kinetic energy of photoelectrons emitted from a metal surface increses from 0.4 eV to 1.2 eV when the frequency of the incident radiation is increased by 40% . What is the work function (in eV) of the metal surface?

The maximum kinetic energy of photoelectrons emitted from a metal surface increses from 0.4 eV to 1.2 eV when the frequency of the incident radiation is increased by 40% . What is the work function (in eV) of the metal surface?

The velocity of the most energetic electrons emitted from a metallic surface is doubled when the frequency nu of incident radiation is double. The work function of this metal is

Work function of a photosensitive metal is 3eV. The wavelength of incident radiations which can just eject photoelectrons from the metal is

If the work function of a metal is 'phi' and the frequency of the incident light is 'v' , there is no emission of photoelectron if
