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