  9. wavelength Back toJeopardy

  10. Unit of measurement for frequency Answer

  11. Hertz (Hz) Back to Jeopardy

  12. This happens when two or more waves interact Answer

  13. Interference Back to Jeopardy

  14. The type of wave that oscillates perpendicular to the direction the wave travels. Answer

  15. transverse Back to Jeopardy

  16. Occurs when two waves interact with each other to make a wave of smaller amplitude Answer

  17. Destructive interference Back to Jeopardy

  18. Occurs when two waves interact to form a bigger wave Answer

  19. Constructive Interference Back to Jeopardy

  20. The type of wave that travels in the same direction as the oscillations Answer

  21. longitudinal Back to Jeopardy

  22. Give an example of a transverse Wave Answer

  23. Ocean waves, electromagnetic waves Back to Jeopardy

  24. Give an example of a longitudinal wave Answer

  25. Sound waves Back to Jeopardy

  26. When a door is only slightly opened, sound will pass from one room to another due to mainly _________________. Answer

  27. diffraction Back to Jeopardy

  28. What occurs when sound waves hit an acoustic tile in an auditorium? Answer

  29. absorption Back to Jeopardy

  30. 5 meters Back to Jeopardy

  31. DAILY DOUBLE!!!! QUESTION

  32. Give the units for the variables used in v= l f

  33. V= m/sl = mf = hertz Back to Jeopardy

  34. The unit for measuring the loudness of sound Answer

  35. Decibel (dB) Back toUnit Review Jeopardy

  36. True or False: The speed of sound is about 343 m/s Answer

  37. True Back to Jeopardy

  38. True or False: Sound waves are slower than light waves Answer

  39. True Back to Jeopardy

  40. True or False: Sound waves travel faster in outer space than in air. Answer

  41. FalseSound depends on three things: a vibrating source to create the sound waves, a medium (such as air) to carry the waves, and a receiver to hear them. Sound waves can't travel through a vacuum. Back to Jeopardy

  42. Give the correct order from slowest to fastest for the speed of sound through these three media.[water, air, wood] Answer

  43. (slowest)Air, water, wood (fastest) Some mediums are better at conducting sound than others. Like all gasses, air is a poor medium for sound waves. Liquids, such as water, are better, and rigid, solid substances, such as iron and stone, are even better, while rubber, cork, and cotton are some examples of poor conductors. Back to Jeopardy

  44. As you decrease the temperature & pressure of air, does the speed of sound increase or decrease? Answer

  45. Decreases! Back to Jeopardy

  46. As the wavelength decreases, the frequency of a wave ________________ Answer

  47. increases Back to Jeopardy

  48. As the loudness of a sound increases, the amplitude of the wave ______________ Answer

  49. increases Back to Jeopardy

  50. The frequency increases when the source and the observer approach each other and decreases when they move apart. Answer
