The frequency \[\left( \mathbf{v} \right)\] of incident radiation is greater than threshold frequency \[\mathbf{(}{{\mathbf{v}}_{\mathbf{0}}}\mathbf{)}\] in a photocell. How will the stopping potential vary if frequency \[\left( \mathbf{v} \right)\] is increased, keeping other factors constant?

Answer:

                  For frequency \[v>{{v}_{0}}\] stopping potential \[\propto v\]. So the stopping potential increases, when the frequency \[v\] is increased.
