In photoelectric effect the work function of a metal is 3.5 eV. The emitted electrons can be stopped by applying a potential of –1.2 V. Then

In photoelectric effect the work function of a metal is 3.5 eV. The emitted electrons can be stopped by applying a potential of –1.2 V. Then

In photoelectric effect, the work function of a metal is 3.7 eV. The emitted electron can be stopped by applying a potential of 1.8 V. Then

If the photoelectric work function of a metal is 5 eV , the threshold frequency of the metal is

If the photoelectric work function of a metal is 5 eV, calculate the threshold frequency of the metal.

In a photo electric experiment, photon of energy 5 eV are incident on a metal surface. They liberate electrons which are just stopped by an electrode at a potential of -3.5V with respect to the metal. The work function of the metal in eV is

The photoelectric work function of a metal is 3 eV . The maximum kinetic energy of the emitted electrons when light of wavelength 3000 Å falls on it is
