Sound 1
An example of a type of longitudinal wave
Sound wave
Pitch is dependant on
Frequency
When a firetruck is moving and its siren is working, an observer behind the firetruck will hear
A lower pitch
A nerve that carries signals of sound waves from the cochlea to the brain
Auditory nerve
The section of a longitudinal wave where air particles are close together and there is a lot of pressure
Compression
The section of a longitudinal wave that has low pressure and particles are further apart
Rarefaction
This part of the ear acts as a funnel and catch sound waves and pass down the ear canal
Pinna
When you have a higher frequency how does the wavelength change?
It is shorter
A section of a wave that measures from the resting position to the crest or the trough
Amplitude
The medium where sound moves the fastest
Solid
When you have a lower frequency how does the wavelength change?
It is longer
This part of the ear presses against the cochlea in the inner ear
Stirrup
Something that causes particles to move
Vibrations
The section of a wave that measures from crest to crest or from trough to trough
Wavelength
When a firetruck is moving and its siren is working, an observer in front of the firetruck will hear
A higher pitch
The part of the ear which is a tunnel that sound waves can travel to get to the middle ear
Ear canal
If a wave moves at a speed of 5 waves per second, what is the frequency?
5 Hertz
The medium where sound moves the slowest
Air/gas
This part of the ear receives sound waves and translate them into something the brain can understand.
Cochlea
The change in wave frequency between a wave source and its observer
