Parts of a Sound Wave
A sound wave is this type of wave, where the direction of movements is parallel
What is a longitudinal wave
The state(s) of matter sound can travel through.. must write any and all that apply
What are solids, liquids, and gases
The name for the outer ear which we feel as skin
What is the pinna
The smallest 3 bones in the human body
The area of a longitudinal wave where the particles are spread further apart
What is rarefaction
Sound travels by
What is vibrating
The structure in the ear that sends vibrations from your outer ear to the middle ear
What is the ear canal
When looking at a sound wave, this tells us how LOUD the sound is
What is amplitude
A sound wave can also be classified as this type of wave, meaning it MUST travel through a medium
What is a mechanical wave
Sound waves move easily and quickly through solids because
What is they are closer together
This part of the ear comes after the ear canal and vibrates in response to sound
What is the ear drum
The last of the 3 bones in the ear to vibrate
What is the stirrup
The area of a longitudinal wave where the particles are closest together
What is compression
As sound waves pass from solids to gases, this happens to the speed
What is it slows down
The part of the ear that vibrates after the stirrup and contains cilia (little hair-like structures)
What is cilia
When looking at a sound wave, this tells us the pitch of a sound
What is frequency
There are 2 ways we can measure the wavelength of a longitudinal wave. Name one of them
What is compression to compression OR rarefaction to rarefaction
Sound particles that are closer together during RARFACTION have this kind of frequency
What is low
The name for the structure that sends the sound messages to your brain
What is the auditory nerve
The snail looking structure in the ear that converts vibrations into messages for the brain to understand
What is the cochlea
