This is the part of the inner ear that sends the sound vibrations to the brain.
What is the cochlea
100
These are created when objects vibrate.
What are sound waves
100
This is a low or high sound.
What is pitch
100
In this type of wave, the particles move up and down (like a ripple in a pond).
What is a transverse wave
100
This is the only type of wave that does not travel through a medium.
What is electromagnetic wave
200
This section of the ear delivers the sound vibrations to the inner ear.
What is the middle ear
200
This is the part of the wave where the molecules are close together.
What is compression
200
This type of sound has a high frequency.
What is a high pitched sound
200
This is the name for the lowest part of a wave.
What is a trough
200
Why do you see lightening before you hear the thunder?
Light waves travel much faster than sound waves. Light waves are electromagnetic waves; they do not travel though a medium.
300
This part of the ear has thinly stretched skin that helps read the vibrations.
What is the ear drum
300
A compression happens when there is ______ pressure.
What is high
300
Hertz (Hz) is the measurement of _______.
What is frequency
300
This describes the number of waves that pass by one spot during one second.
What is frequency
300
Describe the Doppler Effect.
A car will sound louder as it travels toward you and softer after it passes you.
400
This is the outermost part of the ear.
What is the pinna
400
This is the part of the sound wave where the particles are spread out.
What is rarefaction
400
Explain why a high pitch sound would cause your ears to hurt.
Fast wavelengths are hitting our ears.
400
This wave moves in a back and forth motion. This describes a sound wave.
What is a longitudinal wave
400
This is a disturbance that travels from one place to another.
What is a wave
500
This is the part of the ear where it is safe to clean with a Q-tip. Ear wax is produced here.
What is the ear canal.
500
See picture on SMART.
What is a wavelength
500
Name 4 steps that enable us to hear.
1. Sound reaches the ear.
2. The ear drum vibrates.
3. The cochlea reads the vibrations and sends them to the brain.
4. The brain tells you what you are hearing.
500
This is the distance from the resting position of a wave to the crest or trough.
What is the amplitude
500
Water, air, and the ground are three __________ that transport waves.
