Parts of the Wave
How high or low the sound of the wave is, or the measurement from the equilibruium to the trough/crest.
Amplitude
Draw a wave with a high pitch but a low sound.
Look at the board.
Look at the following information about the whistles blowing foam balls:
Whistle 1: 5 centimeters
Whistle 2: 2 centimeters
Whistle 3: 3 centimeters
Put the following in order from the least amount of energy to the greatest.
Whistle 2, Whistle 3, Whistle 1
What does all sound wave?
Vibrations
The number of waves in a given period or time
Draw a transverse wave.
Look at Board
Without Air can you hear sound?
No.
The higher the amplitude the ______ the sound is.
Louder
The very bottom part of the wave under the equilibrium.
Trough
Draw a longitudinal wave.
See Board
What does sound move through?
Air
Look at the following information about the whistles blowing foam balls:
Whistle 1: .5 centimeters
Whistle 2: .1 centimeters
Whistle 3: .6 centimeters
Which of the Wistles released the most energy when blown?
Whistle 3
This determines the pitch of the wave also known asd the distance between crest.
Wavelength
Draw a wave with 4 crest.
See board
What makes up a high volume?
The higher amplitude.
When the sound gets louder what increases?
Amplitude
The Middle line that is in the middle of the wave, also known as the line of origin.
Equilibruium
Draw a wave that has a low pitch, but a high volume.
Look at Board
Which of the following correctly matches up the wave on the board?
1: The wave has a high pitch but a medium volume.
2: The wave has a low pitch but a high volume.
3: The wave has a low pitch but a low volume.
3: The wave has a low pitch but a low volume.
If the wavelengths are far apart is the pitch higher or lower?
