Question:medium
If the energy of the incident radiation on a metal is increased by $10%$, the kinetic energy of the emitted photoelectrons increases from $0.5,eV$ to $0.75,eV$, then the work function of the metal is
If the energy of the incident radiation on a metal is increased by $10%$, the kinetic energy of the emitted photoelectrons increases from $0.5,eV$ to $0.75,eV$, then the work function of the metal is
Show Hint
Physics Tip: Any increase in photon energy directly increases maximum kinetic energy by the same amount because work function remains constant.
