Which conclusion is most creditworthy for Apply Double Slit Relationships To Fringe Spacing?.
- A.A. The conclusion follows from apply double-slit relationships to fringe spacing and states the physical consequence for Interference without changing the assessed idea.
- B.B. The conclusion repeats the question but gives no physics reason.
- C.C. The conclusion is based on a related but different A-Level Physics process.
- D.D. The conclusion is longer, but it does not use the tested relationship.
Model answer
What a good answer should say
- Conclusion Test answer 222b2a: A.
- The conclusion follows from apply double-slit relationships to fringe spacing and states the physical consequence for Interference without changing the assessed idea.
- is correct because it matches Apply double-slit relationships to fringe spacing.
- through phase difference, path difference, stationary wave, progressive wave.
Explanation
Why this works
Stem being answered: Which conclusion is most creditworthy for Apply Double Slit Relationships To Fringe Spacing? Route focus: waves / Refraction Diffraction And Interference.
Key vocabulary for this item: double, slit, relationships, fringe, spacing. Option check: keep Conclusion Test answer 222b2a: A because it matches the stem; reject alternatives that change double, slit, relationships or use a neighbouring model.
The explanation should keep the answer tied to these exact words rather than a general physics summary, using units, graph evidence or equation reasoning only when they are relevant to the stem.
