Science Vocabulary

5. Wave a wave that transfers energy perpendicular to its medium. The energy moves in one direction while the medium moves at a right angle to it
7. material through which waves travel
10. the location of objects by reflected sound, in particular that used by animals such as dolphins and bats
11. the lowest point of a transverse wave
12. the apparent bending of waves around a small obstacle
13. a disturbance that carries energy through matter or space
16. Wave a wave that requires a medium in which to travel and carry energy
17. parts where the waves are spread out
19. a repeated back and forth or up and down motion
20. to bounce off

1. parts where the waves are close together
2. the ability to do work
3. vibrations that travel through the air or another medium and can be heard when they reach a person’s or animal’s ear
4. the highest point of a transverse wave
6. measure of wave energy; the distance between a wave’s resting point and the top or crest of a wave
8. the quality of a sound made by the number of vibrations (the highness or lowness of a sound)
9. Wave waves that move the medium parallel to the direction in which the waves travel
14. the change in direction of a wave due to a change in its medium
15. the distance between two corresponding parts of a wave
18. 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
21. a sound or series of sounds caused by the reflection of sound waves from a surface back to the listener
