Across
  1. 2. the angle made by a reflected ray with a perpendicular to the reflecting surface
  2. 3. occurs when the maxima of two waves add together, so that the amplitude of the resulting wave is equal to the sum of the individual amplitudes.
  3. 6. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
  4. 7. a force that squeezes something together
  5. 10. measure of the bending of a ray of light when passing from one medium into another.
  6. 11. a substance or material that can carry a wave
  7. 13. A ray of light that hits a surface
  8. 15. a wave with a repeating continuous pattern which determines its wavelength and frequency
  9. 17. wave combination of two waves moving in opposite directions, each having the same amplitude and frequency
  10. 18. The ray that bounces back
  11. 23. the point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position.
  12. 25. a decrease in the density of something
  13. 26. The sensation of a frequency
  14. 27. relatively large selective response of an object or a system that vibrates in step or phase, with an externally applied oscillatory force
  15. 29. the attribute that wave oscillations have a definite direction relative to the direction of propagation of the wave
  16. 30. light that has the same wavelength so it is one color
  17. 32. the fraction of a period (i.e., the time required to complete a full cycle) that a point completes after last passing through the reference, or zero, position.
  18. 33. Reflection the reflection of light from a surface such that an incident ray is reflected at many angles, rather than at just one angle
  19. 34. the time for a particle on a medium to make one complete vibrational cycle
  20. 35. the point on the medium that exhibits the maximum amount of negative or downward displacement from the rest position
  21. 38. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant, for the light of a given colour and for the given pair of media
  22. 39. the net effect of the combination of two or more wave trains moving on intersecting or coincident paths
  23. 41. wave motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance
  24. 42. a region of maximum amplitude situated between adjacent nodes in a vibrating body
  25. 43. abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums
Down
  1. 1. when two or more waves overlap in space, the resultant disturbance is equal to the algebraic sum of the individual disturbances
  2. 4. the entire distribution of electromagnetic radiation according to frequency or wavelength
  3. 5. Wave wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave
  4. 8. a statement in optics
  5. 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
  6. 12. the angle between the direction of motion of the wave and a line drawn perpendicular to the reflecting boundary
  7. 14. Light waves from a moving source experience the Doppler effect to result in either a red shift or blue shift in the light's frequency
  8. 16. the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position
  9. 19. the spreading of waves around obstacles
  10. 20. observed when a wave is not confined to a given space along the medium
  11. 21. the number of waves that pass a fixed point in unit time
  12. 22. movement back and forth at a regular speed
  13. 24. occurs when the maxima of two waves are 180 degrees out of phase
  14. 28. the wave movement
  15. 31. reflection such that the angle of reflection of the light is equal to the angle of incidence and on the opposite side of the normal to the point of incidence
  16. 36. a single disturbance that moves through a transmission medium
  17. 37. Wave a wave that is not capable of transmitting its energy through a vacuum
  18. 40. a point along a standing wave where the wave has minimum amplitude
