Potential Energy and Wave Energy

Potential energy is energy that a system has because of how its parts are arranged, or energy that an object has because of where it is located. There are numerous types of potential energy, corresponding to various types of forces:

Wave energy is energy that is transmitted by waves. For some kinds of waves, the transmission of energy involves oscillations between kinetic and potential energy. The energy of water waves, for instance, oscillates between kinetic energy and gravitational potential energy as the water rises and falls. Similarly, longitudinal waves travelling through a “slinky” spring involve oscillations between kinetic energy and elastic potential energy. For electromagnetic waves (e.g. visible light, radio waves, microwaves, x-rays), the transmission of energy involves oscillations between two different aspects of electromagnetic potential energy: the electric field and the magnetic field.
