Across
- 3. the number of waves that pass a fixed point in unit time.
- 4. the distance traveled by a given point on the wave 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 change in frequency of a wave in relation to an observer who is moving relative to the wave source.
- 11. a wave vibrating at right angles to the direction of its propagation.
- 13. occurs at any location along the medium where the two interfering waves have a displacement in the opposite direction.
- 14. regions of high pressure due to particles being close together
- 15. the spreading of waves around obstacles
Down
- 1. term used by scientists to describe the entire range of light that exists
- 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. a kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously
- 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
