Cool Waves

3. abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums
5. the distance a wave travels in a given amount of time
6. the flow of energy at the speed of light
8. interference that occurs at any location along the medium where the two interfering waves have a displacement in the opposite direction
11. the change in direction of a wave passing from one medium to another
12. the substance that transfers the energy, or light from one substance to another substance or from one place to another or from one surface to another
13. Waves that cause a medium to move perpendicular to the direction of that wave.
14. the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position
15. the number of waves that pass a fixed point in a given amount of time

1. the spreading of waves around obstacles
2. when the maxima of two waves add together so that the amplitude of the resulting wave is equal to the sum of the individual amplitudes
4. the entire distribution of electromagnetic radiation according to frequency or wavelength
7. wave where the particle motion is in the same direction in which the wave is propagating
9. the distance between identical points
10. an effect produced by a moving source of waves in which there is an apparent upward shift in frequency for observers
