| Definition | Term |
| When a wave hits a surface and bounces back | |
| When a wave moves around a barrier or through an opening and then bends and spreads out | |
| Points of zero amplitude on a standing wave | |
| Waves that move the medium at right angles to the direction in which the waves travel | |
| The low part of a transverse wave | |
| The high part of a transverse wave | |
| Type of interference that produces a wave with a smaller amplitude | |
| A disturbance that transfers energy from place to place | |
| Interaction that occurs when waves meet | |
| The distance from rest position to crest or trough | |
| The parts of a longitudinal wave that are spread apart | |
| An increase in the amplitude of a vibration that occurs when external vibrations match an object's natural frequency | |
| The distance from crest to crest or from trough to trough | |
| Are surface waves longitudinal, transverse, or both? | |
