Top best answers to the question «What happens to the energy of a wave»
The energy transported by a wave is directly proportional to the square of the amplitude. So whatever change occurs in the amplitude, the square of that effect impacts the energy. This means that a doubling of the amplitude results in a quadrupling of the energy.
- More specifically, the wave is transferring its energy to the atoms and molecules that make up the absorbing material. This transferred energy gets the atoms and molecules vibrating, and the vibration in turn releases that energy in the form of heat.
