Across
- 4. what occurs when waves overlap and combine to form a new wave
- 6. what occurs when crest overlaps crest and trough overlaps troughs
- 8. passage of light through an object
- 9. the change in direction of a wave when it travels by the edge of an object or travels through an opening
- 10. the concept that the angle of incidence equals the angle of reflection
- 11. vibration is in the direction of travel
Down
- 1. what occurs when a crest of one wave overlaps the trough of another wave.
- 2. a wave that requires a medium through which to travel
- 3. bouncing of a wave off a surface
- 5. vibration is at right angle to wave travel
- 7. transfer of energy by a wave to the medium through which it travels
