What kind of wave is sound?

• Mechanical

• Longitudinal

What is the first step of hearing a sound?

• You don't hear it at all

• The middle ear transmits sound waves inward

• The sound waves make the eardrum vibrate

• The outer ear funnels sound waves into the ear canal

Does changing the amplitude change the pitch of sound?

• Yes

• No

• Maybe

• It depends on the wavelength

Does the frequency change the pitch of a sound?

• Yes, it does

• No

• Frequency has nothing to do with pitch

What are the three smallest bones in your ear?

• You have no small bones

• the eardrum, the stirrup, and the cochlea

• The hammer, the anvil, the stirrup

• You have three hammers

What does increasing the wavelength do to the pitch?

• Nothing

• Makes the pitch lower

• Makes the pitch higher

• They cancel out each other

Why doesn't sound travel in a vacuum?

• It needs a medium to travel through

• It does travel through a vacuum

• There is no such thing as a vacuum

When you change the radio station what property of waves are you change?
