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