Physical Science Chapter 15

2. the max distance that the particles of a wave's medium vibrate from their rest position
5. a wave that consists of oscillating electric and magnetic fields, which radiate outward at the speed of light
10. a wave in which the particles of the medium move perpendicularly to the direction the wave is traveling
12. the highest point of a wave
13. interference a superposition of several waves that produce an intensity equal to the differnece of the intensities of the individual waves
14. the number of cycles or vibrations per unit of time; also the number of waves produced in a given amount of time
15. the distance from any point on a wave to an identical point on the next wave
16. waves a pattern of vibration that stimulates a wave that is standing still
17. an observed change in the frequency of a wave when the source or observer is moving
19. a physical environmental in which phenomena occur

1. a wave in which the patciles of the medium vibrate parallel to the direction of wave motion
3. a change in the direction of a wave when the wave finds an obstacle such as an opening
4. a wave that requires a medium through which to travel
6. waves a superposition of several waves that produce an intensity equal to the sum of the intensities of the individual waves
7. the time that it takes a complete cycle or wave oscillation to occur
8. the bending of a wave front as the wave front passes between two substances in which the speed of the wave differs
9. the combination of several waves that result in a single wave
11. the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through
18. the lowest point of a wave
