Across
- 6. Spectrum: the range of wavelengths or frequencies over which electromagnetic radiation extends
- 8. when waves bounce back
- 9. the lowest part of a wave
- 10. Waves: waves that only travel through matter: must use a MEDIUM to travel. There are two types of waves:
- 11. the highest part of a wave

- 4. waves travel side to side as the matter travels up and down.. Ex. slinky moving up and down
- 5. a disturbance that transfers energy through matter or through space
- 7. when waves bend
- 13. height: the vertical distance from the top of the crest to the bottom trough
