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