| A | B |
|---|
| fixed point | position of the wave at rest |
| amplitude | height of the wave from fixed point to crest, or trough |
| microwave | example of an electromagnetic wave |
| crest | highest point, peak of the wave |
| electromagenetic | wave that does not require a medium |
| reflection | the bouncing back of a wave after it strikes a smooth surface |
| frequency | measures the number of waves that pass in a certain amount of time |
| sound | example of a mechanical wave |
| wavelength | the length of one wave crest to the next wave crest, or from trough to trough |
| mechanical | wave that require a medium to travel |
| transmission | when a wave passes through a medium |
| absorption | when a wave is taken in by a medium |
| wave | a repeated pattern with a wavelength, amplitude, and frequency |
| medium | material or matter that a wave moves through |
| trough | lowest point, or peak of the wave |
