In Einstein's picture, radiation travels as:
AEnergy quanta
BSteady waves
CWarm fluids
DFree atoms
Answer & Solution
Correct answer: A. Energy quanta
1. Energy is not spread smoothly over the wavefront.
2. It arrives in discrete packets instead.
3. Those packets are quanta, now called photons.
4. So the answer is energy quanta.
