Travelling Waves

A wave is a disturbance that propagates from its source, repeating itself periodically, and is typically associated with simple harmonic motion. Mechanical waves are governed by Newton's laws and require a medium to travel. A medium is a substance in which a mechanical wave propagates, and the medium produces an elastic restoring force when it i...

When a stone is thrown on the surface of a calm lake, we see circular rings form and spread out from the drop point. These circular rings observed on the water surface are an example of wave motion.

Wave motion is a disturbance that propagates from a state of rest or equilibrium without bulk motion of matter.

Traveling waves can be...
