| Term | Definition |
|
Wave length |
the length from one crest to another |
|
Amplitude |
the maximum distance the medium moves away from the rest position |
|
Frequency |
How many crests there are over a certain area |
|
Period |
refers to the time in which it takes to do something |
|
Longitude wave/ Primary Wave/ Compressional Wave/ P-wave |
a wave inwhuch paticles if the medium move in a direction PARALLEL to the direction which the wave moves |
|
Transverse/ Secondary Wave/ S-Wave |
a wave in which particles of the medium move in a direction PERPENDICULAR to the direction which the wave moves |
|
Rest Position |
the point where the wave is not moving- a strait line in the middle of the wave |
|
Surface Wave |
a wave in which particle of the medium undergo a circular motion |
|
Constructive Interference |
1. 2 waves appraoach each other 2. New crest is the sum of both waves 3. waves go through as if they never met |
|
Refraction |
Wave enters a new medium at an angle. One side of the wave changes speed before the other side/ ncausing wave to bend---- When no angle/ no refraction |
|
Diffraction |
When a wave move around or through an opening in a barrier it bends and spreads out |
|
Reflection |
When an object/wave hits surface which it cannnot pass through--- it bounces back |
|
Doppler Effect |
when a sound/light wave moves, the frequency of the wave changes |
|
Standing Waves |
If incoming wave and a reflected was have just the right frequency they produce a combined wave that appearsto stand still |
|
nocles-- |
(0) Zero amplitude, evenly spaced |
|
Antinodeds-- |
max amplitude, 1/2 way between node, max energy |
|
Sound Waves |
Sound is a disturbance that travels through a medium as a longitudinal wave |
