Question
- A. Lenses (physics only): medical or industrial application in a medical ultrasound scan
- B. Lenses (physics only): a generic statement that ignores reflected pulses, timing and boundary echoes
- C. Lenses (physics only): a boundary mistake that confuses sound reflection versus electromagnetic imaging
- D. Lenses (physics only): a different Unit 4.6 idea from outside Lenses (physics only)
Answer
The correct answer is Lenses (physics only): medical or industrial application in a medical ultrasound scan.
Explanation
Lenses (physics only): 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 Lenses (physics only). It avoids the common boundary error of sound reflection versus electromagnetic imaging while keeping the learning objective visible.
Common mistake
Lenses (physics only) common mistake 1
Giving a vague answer instead of directly addressing: (Physics only) Describe how a convex lens can form a real image..
Answer by clearly explaining how to (Physics only) Describe how a convex lens can form a real image..
