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