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