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