| A | B |
|---|
| amplitude | measure of the energy carried by a wave |
| compressional wave | matter in the medium moves back and forth in the direction the wave travels |
| crest | highest point of a transerve wave |
| diffraction | bending of waves around a barrier or as they pass through an opening |
| frequency | how many wavelenghts pass a fixed point each second; hertz (Hz) |
| interference | when 2 or more waves overlap and combine to form a new wave |
| medium | an material that a wave transfers energy through |
| rarefraction | least dense region of a compressional wave |
| refraction | bending of a wave as it changes speed, moving from one medium to another |
| resonance | ability of an object to vibrate by absorbing energy at its natural frequency |
| standing wave | type of wave that forms when waves of equal wavelength and amplitude (going in opposite directions) continuously interfere with each other. |
| transverse wave | where the matter in the medium moves back and forth at right angles to the direction that the wave travels |
| trough | lowest point of a transverse wave |
| wave | rhythmic disturbance that transfers energy through matter or space |
| wavelength | distance between one point on a wave and the nearest point just like it on the following wave |
