100 – Sounds like Vocab Sound waves are this type of wave What is longitudinal?
200 – Sounds like Vocab Daily Double Our subjective impression of the frequency of a sound is called this What is pitch?
300 – Sounds like Vocab In a sound wave traveling through air a point of lower pressure is called What is rarefaction?
400 – Sounds like Vocab The place where one can touch a standing wave on a rope without disturbing the wave What is the node?
500 – Sounds like Vocab Sound waves with frequencies below the normal range (< 20 Hz) are called this What are infrasonic waves?
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
200 - Speedy Sound Sound waves travel fastest through this type of medium What are solids?
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
400 - Speedy Sound The speed of sound in dry air at 0 degrees Celsius is approximately… What is 330 m/s?
500 - Speedy Sound For every degree Celsius increase the speed of sound increases by… What is 0.6 m/s?
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?
200 - Naturally it's vibrating When objects vibrate at their natural frequency, this occurs? What is resonance?
300 - Naturally it's vibrating When an elastic material is disturbed it produces sound waves @ this frequency What is its natural vibrating frequency?
400 - Naturally it's vibrating How do you know the frequency of a tuning fork? What is read the value printed on it?
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%?
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?
200 – Here’s my Number The relationship between frequency and wavelength What is inversely proportional?
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
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?
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?
100 - So call me wavy Define period. What is the time it takes to complete one cycle?
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?
300 - So call me wavy The units of wavelength What are meters?
400 - So call me wavy An example of a transverse wave What is microwave, radio, light, or any electromagnetic wave?
500 - So call me wavy Define interference What is the result of two waves being in the same place at the same time?
