Absorption of the sound beam is highest in :

The sensitivity of transducers that create short duration pulses is likely to be ________ that of transducers that create long pulses.

Which of the following would define the beam’s intensity at the location where it is maximum? 

Snell’s law determines the amount of:

A pulsed wave transducer has a resonant frequency of 5 Mhz.  The lowest frequency in the pulse is 2 Mhz and the highest is 8 Mhz.  What is the Q factor?

Which type of transducer have a greater bandwidth?

A sound wave is created by a transducer, reflects off an object, and returns to the transducer.  The go return time is 26 µs.  What is the total distance that the pulse traveled?

All of the following correctly describe an imaging transducer except:

A pulsed wave transducer has a resonant frequency of 5 Mhz.  The lowest frequency in the pulse is 2 Mhz and the highest is 8 Mhz.  What is the main frequency?

If an echo returns 104µs  after a pulse was emitted by a transducer, at what depth is the struscture that produced the echo located?
