I don't see the diagram, so I can't pick A or B. Please either upload the picture or describe the two waves (their amplitudes, wavelengths/frequencies and what type of wave they are).
Quick guide so you can tell which has more energy:
- For mechanical waves on a string or sound waves, the energy carried ∝ amplitude^2 and also depends on frequency (for a sinusoidal wave the average energy ∝ A^2 ω^2, where ω = 2πf).
- For electromagnetic waves (classical intensity) the energy flux ∝ (electric-field amplitude)^2.
- For photons (quantized EM energy) energy per photon = hf, so higher frequency (shorter wavelength) means more energy per photon; amplitude controls number of photons (intensity) not energy per photon.
If you upload or describe the waves I’ll determine which has the greatest energy.
