In an experiment on photoelectric effect, a student plots stopping potential V ₀ against reciprocal of the wavelength of the incident light for two different metals A and B . These are shown in the figure. Looking at the graphs, you can most appropriately say that:

Options

  1. AWork function of metal B is greater than that of metal A
  2. BFor light of certain wavelength falling on both metal, maximum kinetic energy of electrons emitted from A will
  3. CWork function of metal A is greater than that of metal B
  4. DStudents data is not correct

Correct answer

D. Students data is not correct

Step-by-step solution

aligned & hc - = eV ₀ & v ₀= hc e - e aligned As the value of 1 (increasing and decreasing) is not specified hence we cannot say that which metal has comparatively greater or lesser work function ( ) .
