alleryThe kinetic energy of the photoelectrons is set by the:
ASize of the plate
BAge of the sample
CEnergy per photon
DNumber of photons
Answer & Solution
Correct answer: C. Energy per photon
1. Intensity changes how many electrons come out, not how fast.
2. Speed is fixed by what each single photon delivers.
3. So the kinetic energy follows the energy of each photon.
4. The answer is energy per photon.
