The Nature of Sound Part 2

In which medium would sound travel the fastest if all of the mediums are at the same temperature?

• Air

• Steel

• Water

• Cork

How does the temperature of a medium affect the speed of sound waves?

• As the temperature of a medium increases, sound waves travel more slowly through that medium

• As the temperature of a medium increases, sound waves travel more quickly through that medium

• As the temperature of a medium decreases, sound waves travel more quickly through that medium

• Temperature does not affect the speed of sound waves

Which part of the ear is involved in amplifying sound?

• Ear canal

• Auditory nerve

• Outer ear

• Anvil

Which part of the ear gathers sound waves?

• Outer ear

• Inner ear

• Middle ear

• Auditory nerve

Through what medium would sound travel the fastest? Water, a steel bar or nitrogen gas? Explain
