Physics Wave Crossword

3. the number of waves that pass a fixed point in unit time.
4. the distance traveled by a given point on the wave (such as a crest) in a given interval of time.
8. the change in direction of a wave passing from one medium to another caused by its change in speed.
9. the apparent difference between the frequency at which sound or light waves leave a source and that at which they reach an observer, caused by relative motion of the observer and the wave source.
11. a wave vibrating at right angles to the direction of its propagation.
13. interference that occurs at any location along the medium where the two interfering waves have a displacement in the opposite direction.
14. a wave vibrating in the direction of propagation.
15. the spreading of waves around obstacles.

1. the range of all types of EM radiation.
2. a substance or material that carries the wave.
5. the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.
6. When two waves of identical wavelength are in phase, they form a new wave with an amplitude equal to the sum of their individual amplitudes.
7. the flow of energy at the universal speed of light through free space or through a material medium in the form of the electric and magnetic fields.
10. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
12. abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums.
