Photoelectric EffectMedium
Question
A point source of light is used in a photoelectric effect. If the source is moved toward the emitting metal, the stopping potential
Options
A.will increase
B.will decrease
C.will remain constant
D.will either increase or decrease
Solution
Stopping potential depends on the K.E. of emitted electron. The K.E. of emitted electron depends on the frequency of the photon, not on the intensity of the photon.
