If u had gone through Davisson and Germer Experiment , u would have dealt WD this
simply Stopping potential is that limiting potential where Photo electric effect does not occur
its always negative

Now, I know that the max kinetic energy of the electrons emitted is
KEmax=hν−eϕem
where ϕem is the work function of the emitter electrode (on the left in the diagram). And my lecturer agrees with that, but he tells us that the stopping potential V0 can be found using
eV0=hν−eϕcol
where ϕcol is the work function of the collector electrode (on the right in the diagram). The emitter and collector electrodes are made from different metals.
What I don't understand is why the stopping potential doesn't depend on the kinetic energy of the emitted electrons.
