Waves

4. the number of times something occurs in a given period of time
8. the distance between neighboring crests, neighboring troughs, or any other neighboring equivalent points of a wave amplitude
11. what happens when two waves interact - can either be constructive (waves add) or destructive (cancel each other out either partially or completely)
12. the bending (change in speed and direction) of a wave as it passes at an angle between media of different densities
13. substance through which waves can travel; plural of medium is media
14. wave in which the motion of the medium is in the same direction as the wave

1. the distance a wave travels in a given amount of time; equal to
2. a wave in which the motion of the medium is perpendicular to the direction of the wave
3. the spreading and bending of waves as they move around a barrier or pass through an opening
5. the lowest part of a wave
6. product of a wave's frequency (f) and its wavelength (λ)
7. deflection (bouncing) of a wave by a surface the wave cannot pass through; echos, mirror images, etc
9. the time required for one full wave to pass a location
10. a repeating motion that travels through a medium
