Ultrasonic Stationary

An ultrasonic wave at 80 000 Hz is emitted into a vein where the speed of sound is about 1.2 km/s?

An ultrasonic wave at 80 000 Hz is emitted into a vein where the speed of sound is about 1.2 km/s. The wave reflects off the red blood cells moving toward the stationary receiver. If the frequency of the returning signal is 80019 Hz, what is the speed of the blood flow?

Roughly 1/2 * c * Δf/f = 0.1425 m/s.
It’s hard to find web references to 2-way sonar frequency shifts, but it’s analogous to the “moving reflector” formula on p. 2-6.3 of the ref.

Vox Ultrasonic $58.94 High Quality Content by WIKIPEDIA articles The Vox Ultrasonic or V268 was a mid to late1960s hollow body thinline electric guitar. The guitars body resembled Gibson thinline models such as the ES335, but otherwise was quite different. The Ultrasonic had no central maple block or set neck, making it more similar in constrction to Fenders thinline guitar, the Coronado. The Ultrasonic, like all late1960s Vox models, was manufactured by the Eko company in Italy.Vox were well regarded as effects box manufacturers and fitted numerous effects into their guitars as well. The Ultrasonic was their highend guitar and therefore had all available effects built in: distortion, treble/bass booster, repeater, palmoperated wahwah, and Etuner.
