2. | the interference that occurs when two waves combine to make a wave with a smaller amplitude |
3. | the rule that the angle of reflection equals the angle of incidence |
4. | the distance between two corresponding parts of a wave |
6. | a point of zero amplitude on a standing wave |
7. | the part of a longitudinal wave where the particles of the medium are closer together |
8. | the bending of waves as they move around a barrier or pass through an opening |
9. | the part of a longitudinal wave where the particles of the medium are far apart |
10. | a wave that moves the medium in a direction perpendicular to the direction in which the wave travels |
12. | a disturbance that transfers energy from place to place |
13. | the bending of waves as they enter a new medium at an angle |
14. | the maximum distance the particle of a medium move away from their rest positions as a wave passes through the medium |
15. | a wave that appears to be standing in one place but it is really two waves interfering as they pass through each other |
18. | the increase of amplitude of a vibration that occurs when external vibrations match an object's natural frequency |
20. | an instrument used to detect and measure earthquake waves |
21. | a repeated back and forth or up and down motion |
24. | the number of complete waves that pass a given point in a certain amount of time |
25. | a longitudinal seismic wave |
27. | a huge surface wave on the ocean caused by an underwater earthquake |
