- 12. a substance that does not allow light to pass through
- 13. the particles vibrate back and forth in the same direction as the wave
Down
- 1. the number of vibrations a wave has in a given time
- 2. a substance that allows light to travel through
- 4. distance that any point on the wave moves from its resting position
- 5. the particles vibrate at right angles to the direction of the wave
