|
What medium does sound of speed travel the fastest?
|
The one with the greater density and greatest resistance to compression- Solids
|
|
|
What is the relationship between wavelength and frequency?
|
frequency is inversely proportional to wavelength
|
|
|
Where does a sound wave travel the fastest?
|
It travels fastest through a liquid medium.
|
|
|
If one of the ends is closed in a standing wave featuring sound, what is the equation for wavelength and frequency and what must n be?
|
Wavelength= 4L/n
Frequency= n/4L*v You must have odd numbers for n |
|
|
What is the beat frequency equation?
|
This is fbeats = absolute value (f1-f2)
|
|
|
In the doppler effect as the sound approaches will frequency increase or decrease
|
Increase
|
|
|
If you are moving as fast as the source then what will the observed frequency be?
|
Observed will equal acutal
|
|
|
What equation explains why a low resistance and a high density give a slow speed of sound?
|
V = sqrt(B/density)
B is the resistance to compression |
|
|
What will increase the decibel level of a sound?
|
Increasing its amplitude
|
