What is the doppler effect?
Ans
a change in frequency caused by the motion of a sound source
In a positive doppler shift the received frequency is [lower, higher] than the
transmitted frequency
Ans
higher
In a negative doppler shift the received frequency is [lower, higher] than the
transmitted frequency
Ans
lower

flow information provides what 4 things?
Ans
1. presence of flow
2. direction of flow
3. speed of flow
4. character of flow
How do you acquire flow information?
Ans
doppler ultrasound
what is the doppler effect?
Ans
the change in frequency/wavelength of a sound that results from motion
