Correct Answer: The square of the amplitude


Solution : The correct option is The square of the amplitude.

The intensity of a wave is proportional to the square of its amplitude. The formula for wave intensity describes this relationship: I∝A2, where I represent the wave's strength. The amplitude of the wave is denoted by A. The intensity of a wave grows quadratically (proportional to the square of its amplitude) as its amplitude increases. Assuming all other elements stay constant, doubling the amplitude of a wave results in a fourfold increase in intensity.
