You are using a transducer that produces a 12MHz soundwave.  The wave is not reaching the desired location of 8 cm deep.  What alteration can you make that will increase the odds that the wave will reach the desired depth?  

When using a 2 MHz transducer, a Doppler shift of 2,000 Hz is reported.  What will happen to the reported Doppler shift if the technologist uses a 4 MHz transducer?
