A student makes a mistake while revising Describe Observations From Cathode Ray Experiments. Which correction is most accurate?.
- A.A. The correction is to keep describe observations from cathode ray experiments separate from the common neighbouring idea in The discovery of the electron, then explain the tested distinction.
- B.B. The mistake is harmless because the two ideas always mean the same thing.
- C.C. The correction is to memorise the wording without explaining the distinction.
- D.D. The answer should move to a different The discovery of the electron topic instead of fixing the misconception.
Model answer
What a good answer should say
- Relationship Map answer fba27a: A.
- The correction is to keep describe observations from cathode ray experiments separate from the common neighbouring idea in The discovery of the electron, then explain the tested distinction.
- is correct because it matches Describe observations from cathode ray experiments.
- through Michelson-Morley, special relativity, time dilation, de Broglie wavelength.
Explanation
Why this works
Stem being answered: A student makes a mistake while revising Describe Observations From Cathode Ray Experiments. Which correction is most accurate?
Route focus: turning-points-in-physics / The Discovery Of The Electron. Key vocabulary for this item: observations, cathode, ray, experiments.
Option check: keep Relationship Map answer fba27a: A because it matches the stem; reject alternatives that change observations, cathode, ray 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.
