| 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.
C) Work function of metal A is greater than that of metal B
D) Students data is not correct
Correct Answer: D
Solution :
[d]   |
| For metal A For metal B |
  |
As the value of  (increasing and decreasing) is not specified hence we cannot say that which metal has comparatively greater or lesser work function  |
