Across
  1. 2. the distance from the line of origin to the crest. Ex: concert speakers produce waves with very large amplitudes.
  2. 4. - the ray that bounces back off a surface. Ex: a laser beam that is reflected off a mirror
  3. 6. - a wave with a repeating pattern in equal intervals of time. Ex: a child on a swing
  4. 7. - the angle of reflection of the light is not equal to the angle of incidence. Ex: bike reflectors
  5. 8. - the pulsation caused by the combination of two waves of slightly different frequencies Ex: two different tuning forks produce beats
  6. 9. - the combination of 2 opposing waves that results in a wave with a decreased amplitude. Ex: a muffler decreases the sound of the engine by sending an opposing sound wave down the exhaust pipe to make it quieter
  7. 11. - the maximum point of a wave. Ex: The highest point of an ocean wave
  8. 14. - the angle between the direction of motion of a wave and the direction of reflection. Ex: the angle between your eyeline to a mirror and what you see reflected
  9. 15. - light that has the same wavelength so it is one color. Ex: laser light
  10. 18. - periodic motion that repeats itself in a regular cycle. Ex: side to side swing of a pendulum
  11. 19. - the change in direction of a wave passing from one medium to another caused by its change in speed. Ex: a pencil in a half full glass of water appears bent
  12. 21. - when a wave strikes an object with the same frequency as it. Ex: opera singers breaking glasses
  13. 24. - a point along a standing wave where the wave has minimum amplitude. Ex: the ends of a guitar string
  14. 26. - combination of two waves moving in opposite directions, each having the same amplitude and frequency. Ex: waves produced by string instruments
  15. 27. - description of the frequency of sound. Violins play a higher pitch than cellos.
  16. 28. - the minimum point of a wave. Ex: when the ocean seems shallow after the crest of a wave crashes
  17. 29. - the combination of 2 waves along the same medium. Ex: when 2 stones are dropped in water and the resulting waves meet.
  18. 30. - the orientation of transverse waves’ oscillations. Ex: polarization of a guitar spring can vary depending on how it is plucked
  19. 33. - how many waves occur in a certain period of time. An A on a violin has a frequency of 440 waves/second
  20. 34. - the length of time it takes to complete one wave. Ex: how long it takes for a child on a swing to return to their original position
  21. 35. - abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums. Ex: light reflected from water
  22. 36. - distance of each period.
  23. 37. - when waves overlap, the resultant disturbance is equal to the sum of the individual disturbances. Ex: playing music on instruments is superposition
  24. 38. - the particles of a medium move in the direction of propagation. Ex: Gamma Rays
Down
  1. 1. - the angle of reflection of the light is equal to the angle of incidence and on the opposite side. Ex: a normal mirror
  2. 3. - a ray of light that strikes a surface. Ex: a lamp’s light hitting the wall
  3. 5. - one disturbance that moves through a system. Ex: dropping a pebble in water
  4. 10. - a point along a medium which undergoes maximum amplitude. Ex:the mouthpiece of a clarinet
  5. 12. - the entire distribution of electromagnetic radiation according to frequency or wavelength
  6. 13. - the combination of 2 waves that results in a wave with an increased amplitude. Ex: when 2 speakers play the same song close to each other, the song sounds louder
  7. 16. - wave movement. Ex: when a guitar string is plucked, the wave propagates down the string
  8. 17. - the spreading out of waves around obstacles. Light waves are refracted in water
  9. 20. - the angle between the normal and incident ray Ex: the angle between a light hitting a table and a line perpendicular to the table.
  10. 22. - change in frequency of a wave in relation to an observer who is moving relative to the wave source. Sound ex: the change in pitch from when an ambulance is moving toward you vs away from you. Light ex: as planets move away from earth, they appear red.
  11. 23. - when light passes through different media n1sinθ1=n2sinθ2 Ex: when light passes through water in a glass
  12. 25. - an angular quantity that can measure the difference between waves. Ex: the sine curve is 90 degrees out of phase with the cosine curve
  13. 31. - on a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray
  14. 32. - measure of how much a material slows down light that passes through it. Ex: acrylic glass has an 1.49 index of refraction
