What establishes the frequency of an ultrasound wave ?
A. The transducer
B. the medium through which the sound travels
C. both A and B
D. neither a or B
A. the transducer
, When a sonographer increases the maximum imaging depth during
an exam, what happens to the frequency?

general manner as sound waves that are audible ?
True
