What does a sound wave look like when it has a low pitch?
It has a low frequency with waves moving slowly and far apart.
Which wave has more energy?

Wave A
If the waves get farther apart, what happens to frequency?
Frequency decreases (gets lower)
The height of the wave is called _______________
amplitude
What does a sound wave look like when it has a high pitch?
It has a high frequency, many waves moving fast and close together
Which wave has more energy?

Wave A
If the waves are closer together, what happens to the frequency?
Frequency increases (gets higher)
When you can hear sound from the hallway, what is happening with the sound?
It is transmitted
What does a sound wave look like when it is a quiet sound?
