  1. Sonic Jeopardy!

  2. Sonic Jeopardy! Final Jeopardy

  3. What is a Wave?

  4. A Wave is a disturbance that transfers energy from place to place. Back to Menu

  5. What are the 2 types of waves? Give an example of each.

  6. Transverse is like a rope. Longitudinal is like a slinky. Back to Menu

  7. Explain how waves are created and give an example. What is a Medium?

  8. Waves are created when a source causes a mediumto vibrate. A Mediumis material that a wave can travel through. Back to Menu

  9. Define Compressionsand Rarefactions. Draw a picture to illustrate your definition.

  10. Compression is when waves are pressed closely together. Rarefaction is where the waves are spread out. Back to Menu Final Jeopardy

  11. Name two of the four basic properties (not wave parts) of waves.

  12. They are Amplitude, Wavelength, Frequencyand Speed. Back to Menu

  13. Draw and diagram a transverse wave. There are 3 primary parts that should be labeled.

  14. Crestis the highest point, the Troughthe lowest. Wavelengthis the distance from one crest to the next. Wavelength Crest Back to Menu Trough

  15. What is Frequency and what is its unit? Draw an example of two waves: one with high frequency, one with low.

  16. Frequency, measured in Hertz(Hz) is the number of waves that pass in a certain amount of time. High Frequency Back to Menu Low

  17. Define Amplitude. How is a bow an example?

  18. Amplitudeis the maximum distance the medium carrying a wave moves from its resting point. Back to Menu Final Jeopardy

  19. What is Reflection?

  20. When an object or wave hits a surface it cannot pass through and bounces back. Back to Menu

  21. What do each of these pictures represent? A B

  22. Diffraction and Reflection Diffraction Reflection Back to Menu

  23. Show how Biff can hear Buff from around the corner. What is this called?

  24. Diffraction: when a wave passes a barrier or opening, it bends and spreads out. Back to Menu

  25. Explain what this picture represents and how it occurs.

  26. Refraction, which is the bending of waves when the go from one medium to another. Changes the speed of the wave. Back to Menu Final Jeopardy

  27. When two or more waves meet, their interaction is called…

  28. Interference. Back to Menu

  29. What are two kinds of Interference? Explain them. DAILY DOUBLE!

  30. Constructive (amplifies the sound) and Destructive(smaller amplitude). Back to Menu

  31. What is this video an example of? Explain.

  32. Resonance occurs when vibrations traveling through an object match the object’s natural frequency Back to Menu

  33. Finish the equations: ? ? ?

  34. ConstructiveDestructive Back to Menu Final Jeopardy

  35. What are two types natural disasters that create powerful waves (one leads to the other…)

  36. An Earthquakecreates seismic waves. An underwater earthquake can trigger a Tsunami. Back to Menu

  37. What is the picture below an example of?

  38. Retroreflection Back to Menu

  39. What is sound? Explain, step by step, how we hear it. Use a tuning fork as an example.

  40. Sound is created by Vibrations. When you strike the tuning fork, it vibrates. The fork hits nearby air molecules, giving them the energy from the fork. Those molecules hit other, which hit others… like dominos! Finally, it reaches your ear. Back to Menu

  41. While walking down the street, you notice an ambulance approaching. How does the sound of the siren change, why, and what is this called?

  42. Doppler Effect means the pitch is higher as the object approaches (sound waves pile up closer), and lower as it passes (waves spread out). Back to Menu Final Jeopardy

  43. 60 30 10 As a ___1___ passes from one ____2____ to another, it slows down. This causes it bend or _____3_____ . ____4____ occurs when a wave cannot pass through an object. The more waves that pass a point in a given time, the higher the ____5____ , which is measured in __6__ . Wave with the same ____7____ can amplify one another, causing _____8_____ interference. m/s2 wavelengthmedium constructive Rarefaction refractwaveHz diffractReflectionfrequency destructive

  44. STOP

  45. As a wavepasses from one mediumto another, it slows down. This causes it bend or refract. Reflection occurs when a wave cannot pass through an object. The more waves that pass a point in a given time, the higher the frequency, which is measured in Hz. Wave with the same wavelength can amplify one another, causing constructiveinterference.
