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