| wave | disturbance that transfers energy through space |
| medium | matter through which a wave travels is called the |
| mechanical wave | a wave requiring a medium |
| electromagntic wave | consists of changing electric and magnetic fields and does not require a medium |
| transverse wave | a wave that causes particles of the medium to vibrate perpendicularly to the direction the wave travels is called a(n) |
| longitudinal wave | A wave that causes particles of the medium to vibrate parallel to the direction the wave travels is called a(n) |
| crest | The highest point of a transverse wave is called the |
| trough | The lowest point of a transverse wave is called the |
| amplitude | The greatest distance that particles in a medium move from their normal positions when a wave passes |
| period | The time required for one full wavelength to pass a certain point. |
