ALonger waves carry more energy
BShorter waves carry more energy
CAll wavelengths carry equal energy
DEnergy depends only on distance
Answer & Solution
Correct answer: B. Shorter waves carry more energy
1. The longer the wavelength, the less energy is carried.
2. Short, tight waves carry the most energy.
3. Wavelength is therefore inversely proportional to the energy of the radiation.
4. Moving a heavy rope in short tight waves takes far more effort than moving it in long wide ones, which is the same relationship.
