Question
- A. ionising and non-ionising radiation: ray-box boundary observation in a loudspeaker and microphone demonstration
- B. ionising and non-ionising radiation: a generic statement that ignores compressions, rarefactions and detected vibrations
- C. ionising and non-ionising radiation: a boundary mistake that confuses sound versus ultrasound
- D. ionising and non-ionising radiation: a different Unit 4.6 idea from outside Types of electromagnetic waves
Answer
The correct answer is ionising and non-ionising radiation: ray-box boundary observation in a loudspeaker and microphone demonstration.
Explanation
ionising and non-ionising radiation: 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.
Common mistake
