In an experiment on photoelectric effect, a student plots stopping potential \[{{V}_{0}}\] against reciprocal of the wavelength \[\lambda \] of the incident light for two different metals A and B These are shown is the figure. |
![]() |
Looking at the graphs, you can most appropriately say that: [JEE ONLINE 25-04-2013] |
A) Work function of metal B is greater that that of metal A
B) For light of certain wavelength falling on both metal, maximum kinetic energy of electrons emitted from A will be greater than those emitted from B.
