An oscillation is a periodic motion that repeats itself in a regular cycle. An oscillating movement is always around an equilibrium point or mean value. It is also known as a periodic motion.

  • The term oscillation denotes something that moves in one direction, then moving back in a repeating pattern.
  • An electromagnetic wave describes an oscillatory motion as the electric field and then the magnetic field take turns to increase to their maximum values and then drop back to zero.
