  3. 100 – Sounds like Vocab Sound waves are this type of wave What is longitudinal?

  4. 200 – Sounds like Vocab Daily Double Our subjective impression of the frequency of a sound is called this What is pitch?

  5. 300 – Sounds like Vocab In a sound wave traveling through air a point of lower pressure is called What is rarefaction?

  6. 400 – Sounds like Vocab The place where one can touch a standing wave on a rope without disturbing the wave What is the node?

  7. 500 – Sounds like Vocab Sound waves with frequencies below the normal range (< 20 Hz) are called this What are infrasonic waves?

  8. 100 – Speedy Sound If the moon blew up, how long would it take for us to hear it? (assuming it did not physically impact the earth) What is – Impossible sound needs a medium to travel through

  9. 200 - Speedy Sound Sound waves travel fastest through this type of medium What are solids?

  10. 300 - Speedy Sound If the speed of 10Hz sound in a certain room is 345m/s what is its wavelength? What is 34.5 m

  11. 400 - Speedy Sound The speed of sound in dry air at 0 degrees Celsius is approximately… What is 330 m/s?

  12. 500 - Speedy Sound For every degree Celsius increase the speed of sound increases by… What is 0.6 m/s?

  13. 100 - Naturally it's vibrating A _____________ is a part of a musical instrument that is forced to vibrate due to the vibration of something near it. What is a sounding board?

  14. 200 - Naturally it's vibrating When objects vibrate at their natural frequency, this occurs? What is resonance?

  15. 300 - Naturally it's vibrating When an elastic material is disturbed it produces sound waves @ this frequency What is its natural vibrating frequency?

  16. 400 - Naturally it's vibrating How do you know the frequency of a tuning fork? What is read the value printed on it?

  17. 500 - Naturally it's vibrating CALCULATOR What is the % difference of an experimental value of 345m/s and a mathematically calculated value of 335m/s? What is 2.94%?

  18. 100 – Here’s my Number This phenomenon explains the apparent change in the observed frequency of a moving sound source What is the Doppler Effect?

  19. 200 – Here’s my Number The relationship between frequency and wavelength What is inversely proportional?

  20. 300 – Here’s my Number Daily Double Doubling the wavelength of a wave will do this to the speed of the wave. What is nothing? – the speed is dependent on the medium

  21. 400 – Here’s my Number The frequency and period of an object that vibrates 75 times in 15 seconds What is 5 hz and 0.2 s?

  22. 500 – Here’s my Number The wavelength of a 361.2-Hz sound wave that travels at 320 m/s in air. What is about 0.89 m?

  23. 100 - So call me wavy Define period. What is the time it takes to complete one cycle?

  24. 200 - So call me wavy The way to measure wavelength What is measure crest to crest, trough to trough, or from any point to the identical point on the next wave?

  25. 300 - So call me wavy The units of wavelength What are meters?

  26. 400 - So call me wavy An example of a transverse wave What is microwave, radio, light, or any electromagnetic wave?

  27. 500 - So call me wavy Define interference What is the result of two waves being in the same place at the same time?
