Question
- A. wave speed: ray-box boundary observation in a loudspeaker and microphone demonstration
- B. wave speed: a generic statement that ignores compressions, rarefactions and detected vibrations
- C. wave speed: a boundary mistake that confuses sound versus ultrasound
- D. wave speed: a different Unit 4.6 idea from outside Waves for detection and exploration (physics only)
Answer
The correct answer is wave speed: ray-box boundary observation in a loudspeaker and microphone demonstration.
Explanation
wave speed: 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.
