Definition

A wave is a disturbance in a medium that carries energy without a net movement of particles. It may take the form of elastic deformation, a variation of pressure, electric or magnetic intensity, electric potential, or temperature.

Introduction of Waves

  • Transfers energy.
  • Usually involves a periodic, repetitive Movement.
  • Does not result in a net movement of the medium or particles in the medium (mechanical wave).
