In traveling wave, energy is propagated in a definite direction and with a
If we whip one end of a rope back and forth,
a traveling wave moves down the rope.
The intriguing feature of this wave is that
all the actual motion is transverse to the overall alignment of the rope.
Think of a wave formed by a crown in a stadium,
in which each spectator successively moves his or her arms up and down in response to a neighbor's motion,
propagating a wave around the stadium perpendicular to the direction of the arm motion,
The wave travels from one side of the stadium to the other side
much faster than any spectator could.
