2Please remember to click on a number on the boardTo return to board click anywhereSound waves are this type of waveWhat is longitudinal?100 Sounds like VocabOur subjective impression of the frequency of a sound is called thisWhat is pitch?200 Sounds like VocabDaily DoubleIn a sound wave traveling through air a point of lower pressure is calledWhat is rarefaction?300 Sounds like VocabThe place where one can touch a standing wave on a rope without disturbing the waveWhat is the node?400 Sounds like VocabSound waves with frequencies below the normal range (< 20 Hz) are called thisWhat are infrasonic waves?500 Sounds like VocabIf 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 through100 Speedy SoundSound waves travel fastest through this type of mediumWhat are solids?200 - Speedy SoundIf the speed of 10Hz sound in a certain room is 345m/s what is its wavelength?What is 34.5 m300 - Speedy SoundThe speed of sound in dry air at 0 degrees Celsius is approximatelyWhat is 330 m/s?400 - Speedy SoundFor every degree Celsius increase the speed of sound increases byWhat is 0.6 m/s?500 - Speedy Sound

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?100 - Naturally it's vibratingWhen objects vibrate at their natural frequency, this occurs?What is resonance?200 - Naturally it's vibratingWhen an elastic material is disturbed it produces sound waves @ this frequencyWhat is its natural vibrating frequency?300 - Naturally it's vibratingHow do you know the frequency of a tuning fork?What is read the value printed on it?400 - Naturally it's vibrating

What is the % difference of an experimental value of 345m/s and a mathematically calculated value of 335m/s? What is 2.94%?500 - Naturally it's vibratingCALCULATORThis phenomenon explains the apparent change in the observed frequency of a moving sound sourceWhat is the Doppler Effect?100 Heres my NumberThe relationship between frequency and wavelengthWhat is inversely proportional?200 Heres my NumberDoubling the wavelength of a wave will do this to the speed of the wave.What is nothing? the speed is dependent on the medium300 Heres my NumberDaily DoubleThe frequency and period of an object that vibrates 75 times in 15 secondsWhat is 5 hz and 0.2 s?400 Heres my NumberThe wavelength of a 361.2-Hz sound wave that travels at 320 m/s in air.What is about 0.89 m?500 Heres my NumberDefine period.What is the time it takes to complete one cycle?100 - So call me wavyThe way to measure wavelengthWhat is measure crest to crest, trough to trough, or from any point to the identical point on the next wave?200 - So call me wavyThe units of wavelengthWhat are meters?300 - So call me wavyAn example of a transverse waveWhat is microwave, radio, light, or any electromagnetic wave?400 - So call me wavyDefine interferenceWhat is the result of two waves being in the same place at the same time?500 - So call me wavyxxxxxxxxxxxxFINAL JEOPARDYCATEGORYPLEASE MAKE YOUR WAGER xxxxxxxx
