Science Vocabulary

2. The lowest point of a transverse wave.
3. The quality of a sound made by the number of vibrations (the highness or lowness of a sound.)
5. Doppler Effect An increase (or decrease) in the frequency of sound, light or other waves as the source and observer move toward (or away from) each other.
6. The change in direction of a wave due to a change in its medium.
12. The location of objects reflected by sound, in particular that used by animals such as dolphins and bats.
14. A sound or series of sounds caused by the reflection of sound waves from a surface back to the listener.
16. Wave A wave that transfers energy perpendicular to its medium. The energy moves one direction while the medium moves at a right angle to it.
18. To bounce off.
19. Wave A wave that requires a medium in which to travel and carry energy.
20. The apparent bending of waves around a small obstacle

1. Parts where the waves are close together.
4. The highest point of a transverse wave.
7. Measure of wave energy; the distance between a waves' resting point and the top or crest of the wave.
8. Distance between 2 crests or troughs.
9. Wave Waves that move the medium parallel to the direction in which the waves travel.
10. Vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.
11. Parts where the waves are spread out.
13. A repeated back and forth or up and down motion.
14. The ability to do work.
15. A disturbance that carries energy through matter or space.
17. Material through which waves travel.
