Parts of a Wave
100
Any material a sound wave travels through.
What is a medium.
100
their is a high frequency and high amplitude.
What is a high pitch and loud sound.
100
the three bones that make up the middle ear.
What are the hammer, anvil, and stirrup.
100
sound travels through this medium 13 times faster than air.
What are solids.
100
this part of a wave determines the loudness of a sound and the amount of energy a wave has.
What is the amplitude.
200
the measure of how well a sound can be heard.
What is loudness.
200
a sound wave with a low frequency, but a high amplitude.
What is low pitch and a loud sound.
200
this part of the ear stimulates nerves, that take electrical signals to the brain, so the sound can be recognized.
What is the inner ear.
200
sound is this type of wave.
What is longitudinal/mechanical.
200
this is the top peak of a wave.
What is the crest.
300
how high or how low a sound is
What is pitch.
300
a sound wave with a high frequency, but a low amplitude.
What is a high pitch and soft sound.
300
this part of the ear, funnels sound from your environment into the ear.
What is the outer ear.
300
when sound waves form areas of higher pressure.
What are compressions.
300
this is the lowest point of a wave.
What is the trough.
400
the unit use to measure the intensity of a sound.
What is decibel.
400
a sound wave with a low frequency and low amplitude.
What is a low pitch and soft sound.
400
which part of the ear helps with balance.
What is the inner ear.
400
when sound waves form areas of low pressure.
What are rarefactions.
400
the positon of the wave when there is no vibration.
What is the center point/rest position.
500
the apparent change in the frequency of a sound.
What is Doppler effect.

the damage that is done to the tiny hair cells in your ear.
What is tinnitus.
500
sounds never run out of energy.
What is false.
500
when frequency increases this decreases.
What is wavelength.
