Photoelectric EffectHard
Question
The anode plate in an experiment on photoelectric effect is kept vertically above the cathode plate. Light source is put on and a saturation photocurrent is recorded. An electric field is switched on which has vertically downward direction
Options
A.The photocurrent will increase
B.The kinetic energy of the electrons will increase
C.The stopping potential will decrease
D.The threshold wavelength will increase
Solution
The electrons will get accelerated in the electric field. Hence, kinetic energy will increase.
