Lesson 1 - Wave Properties

3. The unit of measure that describes the intensity or loudness of sound. (dB)
6. The maximum distance that the wave moves from its rest position.
9. A space completely empty of matter.
13. The distance from one point on a wave to the same point on the next wave.
14. A wave that travels only through matter.
15. The highest points on a transverse wave.
17. Things that change at the same rate, so that the relationship between them does not change.
18. Happening quickly.
19. The number of times the pattern repeats in a given time.
22. The ability to cause change.
25. The state of something not moving.
27. How you perceive the energy of a sound wave.
29. A break or crack in the rocks of Earth’s crust where movement can take place.

1. A wave that causes the particles in a medium to move parallel to the direction that the wave travels.
2. Forming a 90-degree angle.
4. A material in which a wave travels.
5. unit The metric system used in science and medicine.
7. A wave in which the disturbance is perpendicular to the direction the wave travels.
8. A longitudinal wave that can travel only through matter.
10. The perception of how high or low a sound seems.
11. To identify the presence of something.
12. To notice or become aware of.
13. A disturbance that transfers energy from one place to another without transferring matter.
16. A shape that has a pointed top and sides that form a circle at the bottom.
20. Position for an undisturbed particle; particles are still in motion here.
21. Two things that are the same distance apart along their whole length.
23. A set of values from least to greatest.
24. The lowest points on a transverse wave.
26. The amount of sound energy that passes through a square meter of space in one second.
28. Responsibility for wrongdoing or failure.
