What type of wave can not travel through space due to the absence of a medium?
sound waves
100
longitudinal waves
What is the other name for a compression wave?
100
How are frequency and energy related?
directly related to one another; higher frequency = more energy
100
Why does volume decrease as you move away from a sound source?
The energy of the sound wave begins to die down

200
Is volume or frequency related to pitch?
Frequency.
200
The changed pitch of the Doppler Effect is due to changes in _______.
wave frequency

The farther away you move from the band room, the lower the volume gets. Is this an example of the Doppler Effect? Explain..
No Loudness is not associated with the Doppler Effect
500
