Increasing the intensity of light leaves the stopping potential:
ADoubled up
BHalved off
CWiped out
DUnchanged
Answer & Solution
Correct answer: D. Unchanged
1. Intensity raises the saturation current.
2. It does not change the energy each photon carries.
3. So the stopping potential stays unchanged.
4. The answer is unchanged.
