Q1
In a wave, if the amplitude is increased, what happens to the energy carried by the wave?
Energy decreases
Energy remains the same
Energy increases linearly
Energy increases with the square of the amplitude
The energy carried by a wave is proportional to the square of its amplitude, so if the amplitude increases, the energy increases with the square of that increase.

Q
Q: In a wave, if the amplitude is increased, what happens to the energy carried by the wave?
Solution: The energy carried by a wave is proportional to the square of its amplitude, so if the amplitude increases, the energy increases with the square of that increase.
Steps: 4
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. More amplitude means more energy.
Step 3: Learn that energy is proportional to the square of the amplitude. This means if you double the amplitude, the energy increases by four times (2 squared).
Step 4: Conclude that if the amplitude increases, the energy carried by the wave also increases, and it increases by the square of the change in amplitude.
