I hear something
The unit used to measure the intensity of sound.
What is a decibel?
In a longitudinal wave, this is the crowded areas.
What are compressions?
This is the highest part of a Transverse wave
What is the crest?
If a high note and a low note travel through the same medium their speed is this. (The same or different?)
What is the same?
What is there's no medium?
This term describes how high or low a sound is.
What is pitch?
In a longitudinal wave, this is the spread out parts.
What are rarefactions?
This is the lowest part of a Transverse wave
What is the trough?
Instrument 1 hits a very high note when Instrument 2 hits a low note. This is the one that has the higher frequency.
Sound traveling through air, water and steel will travel fastest through this medium.
What is steel?
Faster than the speed of sound in a given medium is called this.
What is a sonic boom?
A wave with a direction of propagation parallel to its direction of oscillation.
What is a longitudinal wave?
This term describes the distance from one crest to the next crest in a transverse wave.
What is wavelength?
Instrument 1 hits a very high note when Instrument 2 hits a low note. This is the one that has the longer wavelength.
What is Instrument 2? (Low note = longer wavelength)
Sound traveling through air, water and steel will travel slowest through this medium.
What is air?
The substance a wave travels through is called this.
What is a medium?
A sound wave is an example of this type of wave
What is a longitudinal wave?
A wave with a direction of propagation perpendicular to its direction of oscillation.
What is a Transverse wave?
The change in pitch of a moving siren is called this.
What is the Doppler Effect?
A sound increases from 40 dB to 70 dB. This is how many times greater the intensity of the sound is?
What is 1000 time greater?
This term describes the changes in frequency of a sound wave produced by a moving source with respect to an observer
What is the Doppler Effect?
This is what happens to pitch when the length of an air column decreases.
What is pitch increases?
