Sound is traveling in a medium and strikes a boundary with normal incidence.  If 63% of the wave’s intensity is reflected back towards the transducer, what percentage is transmitted?  _____ % (only type in the number, do not spell it out)

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?

attenuation encompassess:

A sound wave is created by a transducer, reflects off an object and returns to the transducer. The imaging depth is 10 cm in soft tissue.  What is the maximum PRF?

With perpendicular incidence, what percentage of the incident beam continues to the next medium?

All of the following correctly describe an imaging transducer except:

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

The dampening material in a transducer improves the systems lateral resolution.
