- 6. a solid, liquid or gas a wave travels through
- 8. electromagnetic energy that causes sunburn
- 9. bouncing of light waves off a surface
- 10. area of a longitudinal wave where the particles are closest together
- 11. a wave in which the particles of the medium vibrate parallel to the direction of wave motion
- 13. (ROY G BIV) the only light waves humans can see
- 16. electromagnetic energy used for heating food quickly
- 18. the number of waves that pass through a given point in a set time
- 21. area of a longitudinal wave where the particles are farthest apart
- 22. height of a wave
- 23. waves bend around small obstacles, or spread out after they pass through small openings
Down
