- interference
- results from the superposition of two or more waves; can be constructive or destructive
- wave
- a disturbance that carries energy through mater or space
- frequency
- the number of complete oscillations a wave makes each second
- periodic motion
- any motion that repeats a regular cycle
- longitudinal wave
- a wave in which the disturbance is parallel to the direction of travel
- refraction
- the change in direction waves experinece at hte boundary between two different media
- period
- the time needed for an object to complete one full cycle of simple harmonic motion
- node
- when waves are superposed, any poitn that dos not expeirnece displacement
- amplitude
- the maximum distance an object in simple harmonic motion moves from equilibrium
- standing wave
- a wave that appears to be standing still, produced by the interference of two traveling waves moving in opposite directions
- antinode
- the point with the largest displacement when two wave pulses meet
- trough
- the lowest point of a transverse wave
- crest
- the highest point of a transverse wave
- transverse wave
- A wave that travels in a direction perpendicular to its displacement
- node
- when waves are superposed, any point that does not experinece displacement which is equal to zero
- wave length
- the shortest distance between two points where the wave pattern repeats
