Question

The speed of sound in human tissue is about 1600m/s. If an ultrasound pulse takes

1.5X10^-4 seconds to travel through a tissue, what is the thickness of the tissue?
(Hint: multiply both sides by .00015/1)

Answer 1

To calculate the thickness of the tissue, you can use the formula:

Thickness = Speed of Sound * Time

In this case, the speed of sound in human tissue is 1600 m/s, and the time it takes for the ultrasound pulse to travel through the tissue is 1.5 x 10^-4 seconds.

So, plug these values into the formula:

Thickness = 1600 m/s * 1.5 x 10^-4 s

Now, perform the calculation:

Thickness = 240 x 10^-4 m

To simplify, convert 10^-4 to scientific notation:

Thickness = 2.4 x 10^-2 m

So, the thickness of the tissue is 2.4 x 10^-2 meters, which is equivalent to 0.024 meters or 2.4 centimeters.
