Traveling+waves

=
 A wave is a disturbance or variation that transfers energy progressively from point to point in a medium. However, the medium is not affected once the wave passes. ======

=
 A traveling wave is a wave that appears to be moving in one particular direction. A traveling wave is also a wave in which the medium moves in the direction of propagation of the wave. However the particles in the medium do not propagate with the wave. ======

=
 Examples of traveling waves are radio waves, light waves, and water waves on the ocean, as well as seismic waves. Radio waves propagate in free space, while light waves propagate in optical fibers, and water waves propagate on the surface of the ocean. ======
