Physics Doppler Exam Questions and Answers 100% Solved What choice relates to the presence of gray shades in a doppler spectrum? Amplitude of the echo Which of the following determines the grayscale in a doppler spectrum? Number of reflectors Blood moving at a velocity of 2m/s creates a doppler frequency of 3000Hz. What will the doppler shift be if the velocity measures 4m/s? 6000Hz Doppler does not always provide a valid estimate of the speed of blood cells because the shift is relate...

Non-directional Doppler/ Non Coherent/ Hand held Doppler - ANSWER-a basic doppler system that simply measures movement, by the presence of a frequency shift (can ONLY detect that) Bi-directional Doppler - ANSWER-uses phase quadrature to distinguish flow direction with a special set of headphones Phase quadrature - ANSWER-separates the echo frequencies to positive and negative shifts and send that data to separate headphones Continuous Wave - ANSWER-always two crystals Continuous Wave...
