Question

The source sent an ultrasonic signal of the frequency of 5 MHz and received two echo-signals with a delay of 60 ms between them. The first echo-signal returned after 40 ms. What is the thickness of the organ from which the signal was reflected if the reflection occurred from opposite sides of the organ? What is the absorption coefficient if the intensities of the echo-signals differ by 1120 times? The speed of the wave is 1450 m / s.

The source sent an ultrasonic signal of the
frequency of 5 MHz and received two echo-signals
with a delay of 60 ms between them. The fırst
echo-signal returned after 40 ms. What is the
thickness of the organ from which the signal was
reflected if the reflection occurred from opposite
sides of the organ? What is the absorption
coefficient if the intensities of the echo-signals
differ by 1120 times? The speed of the wave is
1450 m / s.
