A sound beam  with an initial intensity of 600mw/cm^2 is incident on an interface and propagates 3 cm in soft tissue. The frequency is 6 MHz. The final intensity after 3 cm will be

What is the depth of reflector in soft tissue if the time of flight is 78 microsecs

If original intensity is 100mw/cm^2 and the change during propagation is 6 dB, what is the final intensity

The shadowing below(distal to) the  the echogenic stones in the image demonstrates all EXCEPT

A sound beam strikes an air/soft tissue boundary at an angle of 60 degrees. Which statement is FALSE ?

An original intensity of 100mw/cm^2 was reduced to 10mw/cm^2. What is the change in dB?

What is the final intensity if an initial intensity of 50mw/cm^2 goes through 6dB of attenuation
