What happens to amplitude when power increases?

Explanation:
Increasing power means more energy is being carried by the wave each second, so the oscillation becomes stronger. In many systems, the power of a sinusoidal wave is proportional to the square of its amplitude (P ∝ A^2). Therefore, when you raise the power, the amplitude grows as well (roughly with the square root of the power increase). So the amplitude increases. The other options don’t fit because higher power does not inherently cause the amplitude to decrease, stay the same, or oscillate.
