The energy carried by a propagating electromagnetic wave comes at the expense of the:
AEnergy of the sunset
BEnergy of the surface
CEnergy of the sample
DEnergy of the source
Answer & Solution
Correct answer: D. Energy of the source
1. Radiation does not create energy out of nothing.
2. The accelerated charge is what pays for it.
3. The energy of the propagating wave comes at the expense of the energy of the source.
4. So the answer is the energy of the source.
