An ultrasound machine uses waves to create images. the machine uses sound waves and which wave interaction? a) diffraction b) interference c) reflection d) refraction

C) Reflection

Explanation:

In ultrasound technique we throw a sound of higher frequency towards the cells or the damaged part and then a detector is placed at the same point.

Now the detector is used to detect the reflected sound of the sound which we projected. Now the part from which detector not detect any sound will be termed as defect.

So in this whole process we need to find the part from which reflected sound is not detected.

So here correct answer must be

C) Reflection

what is the question because that is not a question.
