Waves

5. 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.
8. the change of direction of propagation of a wave when it meets a boundary
10. Radiation that has both electric and magnetic fields and travels in waves.
11. the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
12. the range of all types of EM radiation.
13. something that is between or in the middle.
14. the spreading of waves around obstacles.

1. occurs when waves come together so that they completely cancel each other out.
2. what happens when two waves overlap in such a way that they combine to create a larger wave.
3. a wave vibrating at right angles to the direction of its propagation.
4. cause the medium to move parallel to the direction of the wave
6. the number of waves that pass a fixed point in a given amount of time.
7. describes how long the wave is.
9. the change in direction of a wave passing from one medium to another caused by its change in speed.
