EASYMCQ SINGLENEET ChemistryPhysical ChemistryAtomic StructureIntro In the photoelectric effect, the number of photoelectrons emitted is proportional to:
0.Intensity of incident beam
1.Frequency of incident beam
2.Velocity of incident beam
3.Work function of the metal
Explanation
Frequency determines whether electrons will be ejected; intensity determines how many electrons are ejected.
