• space

A ___________ is required for sound energy to move through.

• pitch

• decibels

• medium

• loudness

Sound intensity (loudness) is measured in what unit?

Why can't you hear in space?

• In space it is too cold for sound to travel.

• You can't hear in space because there are no rocks for the sound to bounce off of.

• There is no medium in space for sound to travel through.

• If you were in space, you really could hear.

What are the two parts of a longitudinal wave?

• Crests and Troughs

• Compressions and Rarefactions

• Pressure and Time

• Hertz and Decibels

How does increasing the length of a vibrating object affect the FREQUENCY of a sound that is produced?

• The frequency would remain the same.

• The frequency would also increase.

• The frequency would decrease.

• There frequency would be ZERO.

How is the speed of sound affected by an increase in air temperature?

• As the temperature increases, the speed decreases.

• As the temperature decreases, the speed decreases.

• Temperature has no affect on the speed of sound in air.
