Waves in PhysicsA series of free High School Physics Video Lessons from Brightstorm online Physics series.
Wave Phase Wave phase is the offset of a wave from a given point. When two waves cross paths, they either cancel each other out or compliment each other, depending on their phase. These effects are called constructive and destructive.
Standing Waves Standing waves, also known as stationary waves, are waves formed by the combination of two waves with equal amplitudes and frequencies. Because of the interference between these waves, standing waves don't travel at all. There are points along the wave, called nodes, which don't seem to move at all but vibrate in place.
Transverse Waves Transverse waves are waves which move particles in a direction perpendicular to the direction of a wave. An example of transverse waves are ocean waves in which water moves up and down, but does not move forward with the wave. The counterparts to transverse waves are longitudinal waves which move particles in the direction that the wave moves.
Longitudinal Waves Longitudinal waves are waves which move particles in the direction of the wave motion. They are the counterparts to transverse waves which move particles parallel to the direction of wave motion.
