Waves

3. .describes the changes in frequency of any kind of sound or light wave produced by a moving source with respect to an observer.
7. .the spreading out of waves as they pass through an aperture or around objects.
8. . the maximum amount of displacement of a particle on the medium from its rest position.
11. . motion in which all points on a wave oscillate along paths at right angles to the direction of
12. . the distance a wave travels in a given amount of time.
14. .the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.
15. . substance or material that can carry a wave.

1. wave. waves where the particle motion is in the same direction in which the wave is propagating.
2. . the entire distribution of electromagnetic radiation according to frequency or wavelength.
4. .a wave of electric and magnetic fields propagating at the speed of light c through empty space.
5. . abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums.
6. . occurs when the maxima of two waves add together.
9. .the number of waves that pass a fixed point in a given amount of time.
10. . a change in the direction of waves as they pass from one medium to another.
13. . occurs when the maxima of two waves are 180 degrees out of phase.
