Across
- 2. the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.
- 3. a mechanical or electronic device that works on the principles of oscillation: a periodic fluctuation between two things based on changes in energy.
- 4. the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.
- 8. an oscillation of matter, and therefore transfers energy through a medium
- 9. any material substance which can propagate waves or energy.
- 10. a type of wave that travels in the direction of the medium
- 14. the change in direction of a wave passing from one medium to another caused by its change in speed.
- 18. when two waves overlap in such a way that they combine to create a larger wave.
- 20. waves where the particle motion is in the same direction in which the wave is propagating.
Down
- 1. when two waves overlap in such a way that they cancel each other out.
- 5. the change in wave frequency during the relative motion between a wave source and its observer.
- 6. the number of waves that pass a fixed point in unit time
- 7. The time it takes for two successive crests (one wavelength) to pass a specified point.
- 11. the minimum value of upward displacement within a cycle.
- 12. the change of direction of propagation of a wave when it meets a boundary.
- 13. a phenomenon in which an external force or a vibrating system forces another system around it to vibrate with greater amplitude at a specified frequency of operation.
- 15. the rate at which it transfers energy divided by the area over which the energy is spread
- 16. shown by the spacing of the waves displayed.
- 17. motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance.
- 19. the maximum value of upward displacement within a cycle.
