Physics Doppler Effect UPDATED Exam
Questions and CORRECT Answers
Doppler Effect - CORRECT ANSWER- ✔✔An apparant change in frequency as a result of a
change in wavelength caused by motion relative to observer
Proportional - CORRECT ANSWER- ✔✔What is the relationship between doppler shifted
frequency and velocity?
Doppler Shift - CORRECT ANSWER- ✔✔Difference in frequency between the frequency
that was transmitted and frequency that was received.
Detected frequency is lower than transmitted frequency - CORRECT ANSWER- ✔✔What
results in a negative doppler shift?
Detected frequency is higher than transmitted frequency - CORRECT ANSWER- ✔✔What
results in a positive doppler shift?
1-10kHz or 20-20,000 Hz - CORRECT ANSWER- ✔✔What is the normal range of doppler
shift?
Proportional - CORRECT ANSWER- ✔✔What is the relationship between doppler shifted
frequency and transmitted(operating) frequency?
Inversely proportional - CORRECT ANSWER- ✔✔What is the relationship between doppler
shifted frequency and propagation velocity?
Fdop= 2fovcos🚫/c - CORRECT ANSWER- ✔✔What is the Doppler Equation?
CW, PW, Color Doppler - CORRECT ANSWER- ✔✔What are the 3 standard doppler
modalities?
, Spontaneous contrast - CORRECT ANSWER- ✔✔Increase reflectivity results in ability to
visualize blood
0 degrees; ➕shift - CORRECT ANSWER- ✔✔Blood flow is directed towards transducer.
What is the angle and doppler shift?
180 degrees; ➖shift - CORRECT ANSWER- ✔✔Blood flow is directly away from the
transducer. What is the angle and doppler shift?
➕shift - CORRECT ANSWER- ✔✔The angle formed between the flow direction and the
steered doppler line is 30 degrees and traveling closer towards transducer. What is the
doppler shift?
➖shift - CORRECT ANSWER- ✔✔The angle formed between the flow direction and the
steered doppler line is 150 degrees and traveling away from transducer. What is the doppler
shift?
90 degrees - CORRECT ANSWER- ✔✔What angle results in no doppler shift?
Specular reflectors - CORRECT ANSWER- ✔✔This causes extremely high amplitude
signals, but low doppler frequency
Wider - CORRECT ANSWER- ✔✔In wall filer effect, the higher the filter # the _____ black
band.
Saturation - CORRECT ANSWER- ✔✔When the clutter signals are not adequately reduced
by the wall filters, this occurs.
