- D. sound waves: a different Unit 4.6 idea from outside Sound waves
Answer
The correct answer is sound waves: medical or industrial application in a medical ultrasound scan.
Explanation
sound waves: medical or industrial application in a medical ultrasound scan is correct because it uses the named evidence from a medical ultrasound scan and stays anchored to Sound waves. It avoids the common boundary error of sound reflection versus electromagnetic imaging while keeping the learning objective visible.
