Across
- 1. when two waves are, or are not, in sync
- 5. the separation of any wave radiation according to wavelength
- 7. a point that does not move (when two waves "combine")
- 8. harmonic motion a periodic motion of a point along a straight line, such that its acceleration is always towards a fixed point in that line and is proportional to its distance from that point
- 10. the expansion of particles between pulses of a longitudinal wave
- 11. motion of the particles is perpendicular to direction of wave travel
- 12. an amount of light, heat, or sound that is reflected by a body or surface
- 15. regular variation in magnitude or position around a central point
- 17. a wave that is an oscillation of matter, and therefore transfers energy through a medium
- 20. a component frequency of an oscillation or wave
- 22. the distance between successive crests of a wave
- 23. number of oscillations/vibrations per unit time
- 26. the net effect of the combination of two or more wave trains moving on intersecting or coincident paths
- 29. when waves spread out as a result of passing through a narrow aperture or across an edge
- 30. magnitude of the maximum displacement from the equilibrium position
- 33. formed by the superposition of two harmonic waves of equal amplitude and frequency travelling through the medium in the opposite direction
Down
- 2. ability for waves to combine or "add up" (then pass through each other)
- 3. line joining (neighbouring) points that have the same phase / displacement
- 4. the angle at which a wave (ray) contacts a barrier or surface (as in reflection)
- 6. amplitude of a pulse in a longitudinal wave
- 9. the action of restricting the vibrations of a transverse wave, especially light, wholly or partially to one direction
- 12. a change in direction of propagation of any wave as a result of its traveling at different speeds at different points along the wave fron
- 13. a type of electromagnetic radiation that allows the human eye to see or makes objects visible
- 14. motion of the particles (energy) is parallel to direction of wave travel
- 16. the ratio of the velocity of light in a vacuum to its velocity in a specified medium
- 18. the distance the wave travels in a given amount of time
- 19. vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear
- 21. a wave in which the medium moves in the direction of propagation
- 24. waves created when electrons change energy levels; includes visible light, gamma waves, etc.
- 25. time taken for one complete oscillation
- 27. an indicator of the direction in which a wave (energy) is travelling
- 28. the magnitude of a quantity, such as Power, per unit area
- 31. a single vibration or short burst of sound, electric current, light, or other wave
- 32. the point in an oscillation at which the velocity is maximum and acceleration is zero
