| particle motion is perpendicular to wave motion | transverse wave |
| particle motion is parallel to wave motion | longitudinal wave |
| occurs where both waves have positive or negative displacement | constructive interference |
| occurs where one wave has positive or negative displacement | destructive interference |
| standing waves are the result of __________ and ___________ | interference, reflection |
| part of a stationary wave that doesn't move | node |
| part of a stationary wave where the largest amplitudes occer | antinodes |
| largest standing wave possible on a string is ____ times the length of the string | 2 |
| largest standing wave possible in a pipe is ______ times the length of the pipe | 4 |
| caused by source moving faster than the waves it creates | bow waves |
| three dimensional wave produced by constructive interference when a source is moving faster than the wave it creates | shock waves |
| a shock wave caused by breaking the sound barrier, follows behind the source at the speed of sound objects that do not normally create sound will creat a sonic boom if moving faster than the speed of soudn | sonic boom |
| sound is a ______ wave | longitudinal |
| when the frequency of a forced vibration on an object matches the natural frequency, a dramatic increase in amplitude occurs, this is known as ________ | resonance |
