| Question | Answer |
|---|---|
| waves carry | energy |
| vibrations move ________ from the source | outward |
| ________ waves can be either transversal or compressional. | mechanical |
| _______ waves can only be transversal. | electromagnetic |
| the two shapes of waves: | transversal or compressional |
| high points in a transversal wave | crest |
| low points in a transversal wave | troughs |
| distance from one point on a wave to the other nearest wave | wavelength |
| # of wavelengths each second | frequency |
| half the distance from crest to trough | amplitude |
| more energy= | longer its amplitude |
