alleryStart learning →Einstein's explanation of the photoelectric effect is described as taking energy quantization:
AIn a circle
BOut of physics
CA step further
DOne step back
Answer & Solution
Correct answer: C. A step further
1. Einstein did not merely confirm Planck.
2. Planck proposed that energy comes in quantized amounts.
3. Einstein's explanation of the photoelectric effect enhanced its acceptance.
4. It took energy quantization a step further.
