Question
- A. ionising and non-ionising radiation: medical or industrial application in a medical ultrasound scan
- B. ionising and non-ionising radiation: a generic statement that ignores reflected pulses, timing and boundary echoes
- C. ionising and non-ionising radiation: a boundary mistake that confuses sound reflection versus electromagnetic imaging
- D. ionising and non-ionising radiation: a different Unit 4.6 idea from outside Properties of electromagnetic waves
Answer
The correct answer is ionising and non-ionising radiation: medical or industrial application in a medical ultrasound scan.
Explanation
ionising and non-ionising radiation: medical or industrial application in a medical ultrasound scan is correct because it uses the named evidence from a medical ultrasound scan and stays anchored to Properties of electromagnetic waves. It avoids the common boundary error of sound reflection versus electromagnetic imaging while keeping the learning objective visible.
Common mistake
Properties of electromagnetic waves common mistake 1
Giving a vague answer instead of directly addressing: Explain that ionising radiation can damage living cells..
Answer by clearly explaining how to explain that ionising radiation can damage living cells..
