Across
- 3. To bounce off
- 5. Wave A wave that transfers energy perpendicular to it's medium the energy moves in one direction while the medium moves in a right angle to it
- 8. The location of objects by reflected sound, in particular that used by animals such as dolphins and bats
- 9. A disturbance that carries energy through matter or space
- 10. The lowest point in a transverse wave
- 11. Doppler Effect An increase or decrease in the frequency of sound, light, or other waves as the source and the observer move toward of away from each other
- 14. An apparent bending between waves because of an obstacle or a opening of a barrier
- 15. A material in which waves travel
- 16. Wave A wave that requires a medium in which to travel and carry energy
- 18. The quality of a sound made by the vibrations; the highness or lowness
- 20. The vibrations that travel through air or another medium and can be heard when reached a human or animal's ear
- 21. The ability to do work
Down
- 1. The distance between two crests or troughs
- 2. A repeated back and forth or up and down motion
- 4. The change in a direction of a wave due to a change in it's medium
- 6. A sound or series of sounds by the reflection of sound waves from a surface back to the listener
- 7. Wave A wave that moves the medium parallel to the direction that the waves travel
- 12. The part of a wave that is far apart
- 13. The part where the waves are close together
- 17. Measure of wave energy; between a wave's resting point and the top or crest of a wave
- 19. The highest point in a transverse wave
