Question
- A. Lenses (physics only): ray-box boundary observation in a loudspeaker and microphone demonstration
- B. Lenses (physics only): a generic statement that ignores compressions, rarefactions and detected vibrations
- C. Lenses (physics only): a boundary mistake that confuses sound versus ultrasound
- D. Lenses (physics only): a different Unit 4.6 idea from outside Lenses (physics only)
Answer
The correct answer is Lenses (physics only): ray-box boundary observation in a loudspeaker and microphone demonstration.
Explanation
Lenses (physics only): ray-box boundary observation in a loudspeaker and microphone demonstration is correct because it uses the named evidence from a loudspeaker and microphone demonstration and stays anchored to Lenses (physics only). It avoids the common boundary error of sound versus ultrasound while keeping the learning objective visible.
