If the speed of sound through the body is 1540 m/s, and the wavelength of the radio waves is 0.3 mm, what i

and the speeddoubles as blood flows through a constricted (narrowed) portion of blood vessel, how much will the reflected frequency change?-a) frequency = velocity / wave length = 1540/ 0.3^-3 = 5.......
1) A Doppler flow meter uses ultrasound signals to search for constrictions in blood vessels.

a) If the speed of sound through the body is 1540 meters/sec, and the wavelength of the radio waves is 0.3 mm, what is the frequency of the signal?

b) If a typical blood flow speed is 0.1 m/sec, and the speed doubles as blood flows through a constricted (narrowed) portion of blood vessel, how much will the reflected frequency change?

-
a) frequency = velocity / wave length = 1540/ 0.3^-3 = 5.13^6 Hz
b) doesnt change because the wave length decreases by the same ration
