If the amplitude of a wave is increased, what happens to its energy? (2019)
Step 1: Understand what amplitude means. Amplitude is the height of the wave from its rest position.
Step 2: Know that energy in a wave is related to its amplitude. Specifically, energy increases with the amplitude.
Step 3: Remember the relationship: Energy is proportional to the square of the amplitude. This means if you double the amplitude, the energy increases by four times.
Step 4: Conclude that if the amplitude of a wave increases, the energy of the wave also increases.
