Wave

The movement of energy from one place to another without any accompanying matter. Sound waves, ocean waves and electromagnetic waves are some of the examples; other, more complicated types of waves can spread in plasmas.

All waves have 4 basic properties which they exhibit; Reflection, Refraction, Diffraction and Interference.

Famous Quotes:

"An ocean traveller has even more vividly the impression that the ocean is made of waves than that it is made of water."

Arthur S. Eddington
