Across
  1. 1. measure of the bending of a ray of light when passing from one medium into another.
  2. 5. abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums.
  3. 6. an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other.
  4. 8. a wave in which the particles of the medium move progressively in the direction of the wave propagation
  5. 10. the time for a particle on a medium to make one complete vibration cycle.
  6. 15. the lowest point below the rest position.
  7. 16. the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.
  8. 18. the substance that transfers the energy, or light from one substance to another substance or from one place to another or from one surface to another.
  9. 23. reflection such that the angle of reflection of the light is equal to the angle of incidence
  10. 25. the change in direction of a wave passing from one medium to another caused by its change in speed.
  11. 26. when one object vibrating at the same natural frequency of a second object forces that second object into vibrational motion.
  12. 28. the range of wavelengths or frequencies over which electromagnetic radiation extends.
  13. 29. a single vibration or short burst of sound electric current, light, or other wave.
  14. 31. the region of maximum amplitude between two adjacent nodes in a standing wave.
  15. 32. the spreading of waves around obstacles.
  16. 33. function of one-dimensional space that moves with constant speed.
  17. 34. the attribute that wave oscillations have a definite direction relative to the direction of propagation of the wave.
  18. 36. a wave that is an oscillation of matter, and therefore transfers energy through a medium.
  19. 38. wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave.
  20. 39. reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection.
  21. 40. decrease in volume of any object or substance resulting from applied stress.
  22. 41. a law stating that the ratio of the sines of the angles of incidence and refraction of a wave are constant when it passes between two given media.
  23. 42. a wave which oscillates in time but whose peak amplitude profile does not move in space.
  24. 43. the maxima of two waves add together
Down
  1. 2. The ray of light that bounces back from the surface of reflection
  2. 3. the angle which an incident line or ray makes with a perpendicular to the surface at the point of incidence.
  3. 4. a wave whose oscillations are perpendicular to the direction of the wave's advance.
  4. 7. the angle made by a reflected ray with a perpendicular to the reflecting surface.
  5. 9. The process of spreading to a larger area or greater number; dissemination.
  6. 10. described as the quality of a sound that allows you to label it as “higher” or “lower” to your ear.
  7. 11. the maxima of two waves are 180 degrees out of phase
  8. 12. the repetitive variation, typically in time, of some measure about a central value or between two or more different states.
  9. 13. states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
  10. 14. for all linear systems, the net response caused by two or more stimuli is the sum of the responses that would have been caused by each stimulus individually.
  11. 17. a ray of light that strikes a surface.
  12. 19. the position of a point in time on a cycle of a waveform.
  13. 20. light that has the same wavelength so it is one color.
  14. 21. the boundary between two spatial regions occupied by different matter, or by matter in different physical states.

  16. 24. the pulsation caused by the combination of two waves of slightly different frequencies.
  17. 27. the point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position.
  18. 30. A node is a point along a standing wave where the wave has minimum amplitude.
  19. 35. segment of one cycle of a longitudinal wave during its travel or motion, the other segment being compression.
  20. 37. distance between corresponding points of two consecutive waves.
