http://www. youtube. com/watch. v=yVkdfJ9PkRQ 1 http://www.youtube.com/watch?v=yVkdfJ9PkRQ 1. A wave is a traveling disturbance. 2. A wave carries energy from place to place.

Waves…

Anatomy of a wave Amplitude: Height or depth of a wave measured from rest position. Indicates how much energy a wave has. Wavelength: Length of one wave measured either from crest-crest or trough to trough.

There are two general types of waves. Transverse Wave: A wave that causes the medium it travels through to vibrate perpendicular to direction of wave motion. Longitudinal Wave (compression): A wave that causes the medium it travels through to vibrate parallel to direction of wave motion.

Longitudinal (compression) waves Longitudinal waves are waves where the medium vibrates parallel to the direction of wave travel. Sound is a longitudinal wave. Longitudinal waves are made up of high pressure areas (wave crest) and low pressure areas (wave trough) called rarefactions. Wavelength (λ)

Longitudinal Wave Transverse Wave

Longitudinal vs. Transverse

Another comparison of transverse waves and longitudinal waves.

Every wave has frequency and period…  

Some other terms to know. Wave pulse: a single half wave produced. Reflection: When a wave bounces off a medium boundary and reverses direction. Refraction: when a wave goes from one substance into another. Medium: The substance a wave is traveling through. http://phet.colorado.edu/new/simulations/sims.php?sim=Wave_on_a_String http://www.physicsclassroom.com/mmedia/index.cfm

Standing Waves Standing waves are produced when transmitted waves interfere with reflected waves. They look like they are staying in place. The green is the transmitted wave and the blue is the reflected wave. The black is the sum of both. Nodes are the point on the wave that is not disturbed. Antinodes are the point of maximum disturbance.
