| Answer |
|
|
| Sound is this type of wave |
Longitudinal Wave |
| The number of waves per second |
Frequency |
| Symbol is f |
frequency |
| time for one wave |
Period |
| Length of one wave |
Wavelength |
| Symbol for length of a wave |
Lambda |
| Name we give to frequency of sound usually in music |
Pitch |
| Measured in decibels |
loudness of sound |
| The property of a wave that loudness depends upon |
Amplitude |
| A change in apparent pitch caused by the motion of the source or reciever |
The doppler shift |
| What actually is passing thru the air when we hear sound |
Pressure Waves |
| The product of a sound's frequency and wavelength |
Velocity |
| What actually causes most sounds |
Vibrating objects |
| The type of resonator with a pressure node at both ends |
Open Tube Resonator |
| The type of resonator which has a pressure anti-node at one end |
Closed Tube Resonator |
| The type of tube which resonates at 1/2, 1, 11/2, 2, wavelengths |
Open Tube Resonator |
| This type of tube resonates at 1/4, 3/4, 5/4 wavelength |
Closed Tube Resonator |
| The quality of a sound or the way a vibration actually sounds to a persons ear |
Timbre |
| Dissonance |
An unpleasant sound |
| Consonance |
A pleasant sound |
| The fundamental frequency |
The lowest frequency which will resonate in a resonator |
| Harmonic |
Higher frequencies which will resonate in the same tube as the fundamental |
| Open pipe (tube) resonator |
A tube which is open at both ends |
| Closed pipe (tube) resonator |
A tube which has one closed end |
| A loud then soft variation in the sounds amplitude caused by interference |
Beat |
| Octave |
The difference in frequency between a fundamental and the first harmonic |
| Overtones |
The name given to the fundamental and all the harmonics |
