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 Lenses (physics only)
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 Lenses (physics only). It avoids the common boundary error of sound versus ultrasound while keeping the learning objective visible.

Giving a vague answer instead of directly addressing: (Physics only) Explain how refraction at lens surfaces changes the direction of light rays..
Answer by clearly explaining how to (Physics only) Explain how refraction at lens surfaces changes the direction of light rays..
