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