Question: In a wave, if the amplitude is increased, what happens to the energy of the wave?

Options:

  1. Energy decreases
  2. Energy remains the same
  3. Energy increases
  4. Energy becomes zero

Correct Answer: Energy increases

Solution: 

The energy of a wave is proportional to the square of its amplitude. Therefore, if the amplitude increases, the energy increases.

Questions & Step-by-Step Solutions

In a wave, if the amplitude is increased, what happens to the energy of the wave?
Correct Answer: Energy increases.
  • 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 how big the wave is. Bigger waves carry 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.
  • Step 4: If the amplitude increases, the energy of the wave also increases.
