  15. I love vocabulary! $500 In musical terms, the frequencies that create these standing waves also known as these Click when you are both ready and the box below will disappear to reveal the correct answer. Back to game board What are harmonics? Click here to watch a video of guys illustrating standing waves in an instrument that is closed at one end  http://www.youtube.com/watch?v=t5y4zdaDFcM

  16. Sound $100 This is how many meters per second the speed of sound will change by if the temperature goes up 30oC Click here for the Scooby Doo theme song while you work  http://www.youtube.com/watch?v=0_C2HJvtRDY Click when you are both ready and the box below will disappear to reveal the correct answer. What is 18 m/s? Since the equation for the speed of sound is 330 m/s + 0.6 oC, you just need to take 30 x 0.6= 18 m/s Back to game board

  17. Sound $200 A 70 decibel sound is perceived to be approximately this many times louder than a 20 decibel sound Click when you are both ready and the box below will disappear to reveal the correct answer. What is 32? The loudness of a sound approximately doubles every 10 decibels, so 2 x 2 x 2 x 2 x 2 = 32 or 25 = 32. Take the free hearing test- click on: http://www.youtube.com/watch?v=4G60hM1W_mk What frequency can you hear up to? ___________Hertz (The frequencies are in kHz on the video  ) Back to game board

  18. Sound $300 the name of what is happening in this picture Click when you are both ready and the box below will disappear to reveal the correct answer. What is a sonic boom? Yes, that is an actual picture. Cool! A sonic boom occurs when an object travels faster than sound! Back to game board See a sonic boom: http://www.youtube.com/watch?v=UyFJpXnKm64 2.5-minute explanation of sonic booms if you are interested: http://www.youtube.com/watch?v=-d9A2oq1N38

  19. Sound $400 In the Speed of Sound experiment, if the same tuning fork was used but the water in the graduated cylinder was warmer, the wavelength would have a) been longer than if the water was cool. b) been shorter than if the water was cool. c) not changed. Click when you are both ready and the box below will disappear to reveal the correct answer. What is a) been longer than if the water was cool? v=fl The frequency would be the same. If the water was warmer, the air above it would be warmer so v would increase meaning that l would also have to increase. Back to game board

  20. Sound $500 Hertz can also be expressed with this unit or combination of units Click when you are both ready and the box below will disappear to reveal the correct answer. Back to game board What is 1/second or wave/second?

  21. Waves in Music $100 the lowest frequency that will produce a standing wave the first picture is a nice illustration of it… Click when you are both ready and the box below will disappear to reveal the correct answer. Back to game board What is the fundamental frequency?

  22. Waves in Music $200 FM stands for this Click when you are both ready and the box below will disappear to reveal the correct answer. Back to game board What is frequency modulation?

  23. Waves in Music $300 Taylor Swift probably knows that these are the next two harmonics for an organ pipe (closed at one end) if the fundamental frequency is 200 Hertz Click when you are both ready and the box below will disappear to reveal the correct answer. What are 600 Hertz and 1,000 Hertz? When an instrument is closed at one end, a standing wave will occur at every odd ¼ of a wavelength, so n= 1,3, 5, etc. Love Taylor Swift? Click here  http://www.youtube.com/watch?v=8xg3vE8Ie_E Back to game board

  24. Waves in Music $400 the second and third harmonic of a violin string if it has a fundamental frequency of 200 Hertz Click when you are both ready and the box below will disappear to reveal the correct answer. Back to game board What is are 400 Hz and 600 Hz?

  25. Waves in Music $500 Like in our Speed of Sound lab- the length of an air column that would resonate with a 261.6-Hertz tuning fork if the speed of sound was 348 m/s Click when you are both ready and the box below will disappear to reveal the correct answer. What is 0.33 meter? Use v=fl to find l. Then you will need to divide that by 4 because the fundamental frequency occurs at ¼ of the wavelength since the tube was closed at one end by the water. Back to game board

  26. Fun with Equations! $100 the period of a 440-Hertz sound Click when you are both ready and the box below will disappear to reveal the correct answer. Back to game board What is 0.002 second? (Because T=1/f)

  27. Fun with Equations! $200 this is the wavelength of 101.3 KDWB FM A song for you to listen to as you calculate : http://www.youtube.com/watch?v=w2WILSQ9lys Click when you are both ready and the box below will disappear to reveal the correct answer. Back to game board What is 2.96 meters? v= 3.0 x 108 m/s (radio waves travel at the speed of light) f= 101.3 x 106 Hz (FM is in MegaHertz) Then use v=fl

  28. Fun with Equations! $300 Mike Myslinski screams and the sound travels to the wall and back in 0.30 second. This is the distance from Mike to the wall if it is 60oF. Click when you are both ready and the box below will disappear to reveal the correct answer. What is 50.9 meters? (Use v = 330m/s + 0.6 oC , don’t forget to convert to Celsius, then use v=Dx/Dt and cut the answer in half because you are finding the distance to the wall) Back to game board

  29. Fun With Equations $400 The Daily Double! You can wager up to as much money as you have. If you get it right, you win the amount you wagered. If you get it wrong, you will lose the amount you wagered. You each write the amount you would like to wager in this square now. When you are ready, click on the box to reveal the question. A fire truck is sounding its siren with a frequency of 250 Hertz and is headed toward you at 25 m/s, this is the frequency will you hear if the speed of sound is 340 m/s What is 269.8 Hertz? (notice is sounds higher as it approaches you…) Back to game board Use f’ = f (v) where v is the speed of sound and vs is the (v-vs) speed of the source of the sound- click to see and hear a demo. http://www.youtube.com/watch?v=imoxDcn2Sgo

  30. Fun with Equations $500 Spongebob Squarepants is trying to yell at Squidward to come and catch jelly fish with him. If the temperature of the water is 76oF, and the wavelength is 3.78 m, this is the frequency of Spongebob’s voice. Feel free to listen to the Spongebob theme song while you calculate- double click on this icon: Click when you are both ready and the box below will disappear to reveal the correct answer. What is 411 Hertz? v = 330 m/s + 0.6(24.2oC) = 345 m/s, but sound travels 4.5 times faster in water so v=4.5 x 345 m/s Then use v=fl Back to game board

  31. Final Jeopardy Do this on the back of your Jeopardy board. You each need to make your wager. If you have no money, you cannot play. If you get it wrong you lose the amount that you wagered. Place your wagers now. Then click to get the question when both of you have placed your wager. The category is….Waves and Sound  Click here once you have placed your wager and are ready to see the Final Jeopardy question. An bucket is dropped down a well that is 130 meters deep. This is the amount of time from when you drop it to when you would hear it hit the bottom if it was 10oF. Show your work. (Answer this carefully. Hint- it requires material from a different chapter.) Click when you are both ready and the box below will disappear to reveal the correct answer. What is 5.6 seconds? You need find the time it takes the bucket to fall Dy= viDt+ 1/2aDt2 Then you need to add that to the time it would take for the sound to come back up which you can find using v = Dx/Dt Thank you for playing. Total up your money and determine the winner in your group. The winner gets a prize.  You both should turn in your Jeopardy board for up to 3 extra credit points on tomorrow’s test.
