We use an ultrasound signal to explore the layer of tissue in which sound travels at a speed of 1450 m/s. If the echo arrives with a delay of 37 ìs, what is the thickness of that layer of the tissue?

Question

The thickness of the tissue layer can be calculated using the formula: thickness = (speed of sound in tissue * time delay) / 2. Here, the speed of sound in tissue is 1450 m/s and the time delay is 37 microseconds (37 x 10^-6 s). Thus, thickness = (1450 m/s * 37 x 10^-6 s) / 2 = 0.026775 m or 2.7 cm.
