  2. A wiggle in time

  3. What is vibration?

  4. The time of a to-and-fro swing

  5. What is period?

  6. Has long been used to control the motion of clocks

  7. What is pendulum’s swing?

  8. Can not exist in one instance

  9. vibration

  10. Depends only on the length of the pendulum and the acceleration of gravity

  11. Period

  12. The to-and-fro vibratory motion

  13. What is simple harmonic motion?

  14. The distance from the midpoint to the crest or trough

  15. What is amplitude?

  16. The distance from the top of one crest to the next one

  17. What is wavelength?

  18. How frequent a vibration occurs

  19. What is frequency?

  20. The high point of a wave

  21. What is a crest?

  22. When waves overlap

  23. What is interference pattern?

  24. When waves overlap and increase amplitude

  25. What is constructive interference

  26. When waves overlap and amplitude decreases

  27. What is destructive interference?

  28. Easiest to see in water

  29. Interference

  30. Where crests of one wave overlaps another

  31. What is in phase?

  32. The nodes of the wave remain stationary

  33. What is a standing wave?

  34. These remain staionary

  35. What is a node?

  36. Have the largest amplitude and are halfway between nodes

  37. What is an antinode?

  38. Are a result of interference

  39. Standing waves

  40. What happens if you increase the frequency

  41. You increase the amount of waves

  42. Wave crests overlap and produce a barrier of compressed air

  43. What is a wave barrier?

  44. Crest overlap at the edges and create a v-shape

  45. What is a bow wave?

  46. A strong pressure wave in any elastic medium

  47. What is a shock wave?

  48. There is an extreme rise in pressure, temperature, and density

  49. Shock wave

  50. When a shock wave passes through matter what is preserved
