If the intensity transmission coefficient (ITC) is 0.74, what will the intensity reflection coefficient (IRC) be?

To determine the intensity reflection coefficient (IRC) when the intensity transmission coefficient (ITC) is given, you can use the principle of conservation of energy in an ultrasound interface. The relationship between the intensity transmission coefficient and the intensity reflection coefficient can be described by the equation:

ITC + IRC = 1

This means that the sum of the intensity transmission coefficient and the intensity reflection coefficient equals 1, since all incident intensity must either be transmitted or reflected.

Given that the ITC is 0.74, you can substitute this value into the equation to find the IRC:

IRC = 1 - ITC

IRC = 1 - 0.74

IRC = 0.26

Thus, the calculated IRC is 0.26, which corresponds to the correct answer. Understanding this relationship is crucial for evaluating the behavior of ultrasound waves at boundaries, ensuring that you correctly interpret and apply concepts related to wave transmission and reflection in clinical practice.
