Gas

100
A reflected sound wave.
What is an echo?
100
When we are talking about frequency, what else do we think about when talking about sound?

Pitch

100

What determines the volume or loudness of a sound wave?

What is amplitude?

100
Three main parts of the ear.
What are the outer, middle, and inner ear?
200

What must a sound wave have to be heard?

A Medium

200

Part of a sound wave where the particles of the medium are squeezed together.

Compression

200

If a wave has a high frequency, what else does it have?

a high pitch

200

What is the definition of amplitude?

The height of the wave

200

Hearing Loss may happen if this is damaged

The ear drum

300

Why isn't there any sound in vaccum/space?

There is no form of matter in space

300
Part of a sound wave where the particles of the medium are spread far apart.
What is a rarefaction?
300

If a wave has a low frequency, what else does it have?

a low pitch

300

If a sound wave has short waves, what can we assume about the wave?

It is a quiet sound

300

Where are the 3 smallest bones in our body located? What are the names?

The middle ear

Hammer, Anvil, Stirrup

400

The medium through which sound travels the fastest and why.

Solids because their particles are close together

400
You need this in order to have sound.
What is a vibration?
400
What is frequency?

The amount of times a wave is created in a given amount of time

400

A unit used to measure how loud a sound is.

What is a decibel?

400

What part of our ear detects vibrations and the pitch of sound waves?

The Cochlea

500

Give a real-life example of sound going through each medium. (you should have 3 examples on your board)

Gas: Alarms, Horns, or Bells

Liquid: Sonar

Solids: ear to a table/voice through a wall

500

What is the definition of "Sound"?

Energy created from the vibration of an object.

500

Looking at 2 waves, how would you compare frequencies?

By counting the number of waves created.
500

Looking at 2 waves, how would you compare the amplitudes?

By looking to see if the wave is short or tall

500

What happens once the sound waves go through the ear canal and enter the middle ear?

the eardrum begins to vibrate
