Question
- A. frequency: medical or industrial application in a medical ultrasound scan
- B. frequency: a generic statement that ignores reflected pulses, timing and boundary echoes
- C. frequency: a boundary mistake that confuses sound reflection versus electromagnetic imaging
- D. frequency: a different Unit 4.6 idea from outside Properties of waves
Answer
The correct answer is frequency: medical or industrial application in a medical ultrasound scan.
Explanation
frequency: 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 Properties of waves. It avoids the common boundary error of sound reflection versus electromagnetic imaging while keeping the learning objective visible.
