For Amplitude and frequency modulation, which definition answer best supports this objective: Distinguish amplitude modulation from frequency modulation?.
- A.Distinguish amplitude modulation from frequency modulation. This is the correct definition focus for Amplitude and frequency modulation
- B.A vague answer that names amplitude modulation but does not apply the A-Level Physics reasoning.
- C.A neighbouring-topic answer that does not belong to Amplitude and frequency modulation.
- D.An answer that reverses the quantity, unit, graph feature, or physical relationship.
Model answer
What a good answer should say
- The correct option is Distinguish amplitude modulation from frequency modulation.
- This is the correct definition focus for Amplitude and frequency modulation.
Explanation
Why this works
This is the correct definition focus for Amplitude and frequency modulation" because it directly supports the approved objective: Distinguish amplitude modulation from frequency modulation. The other options are incorrect or weaker because they are vague, outside Amplitude and frequency modulation, or confuse a nearby A-Level Physics quantity, model, unit, graph feature, or conclusion.
