I can’t see the diagram you have — could you upload it or describe the amplitudes of the two waves?
General rule you should use: the energy (or intensity) of a sound wave is proportional to the square of its amplitude. So whatever the ratio of amplitudes is, square that ratio to get the ratio of energies, and choose the bar graph whose bar heights match those squared values.
Examples:
- If Wave A’s amplitude is twice Wave B’s, energy ratio = 2^2 : 1^2 = 4 : 1 → choose the bar graph with A’s bar four times as tall as B’s.
- If A’s amplitude is three times B’s, energy ratio = 9 : 1, etc.
If you send the image or the amplitudes, I’ll pick which of your four choices is correct.
