Which statement gives the clearest definition needed for Discuss How The Experiment Supports Constant Light Speed?.
- A.A. It defines discuss how the experiment supports constant light speed in the context of Michelson-Morley experiment, using the key quantity or physical process before any example is added.
- B.B. It only gives a broad topic heading for Special relativity.
- C.C. It swaps the definition with a calculation shortcut.
- D.D. It describes a result but not the underlying physics idea.
Model answer
What a good answer should say
- Graph Reading answer 933d0d: A.
- It defines discuss how the experiment supports constant light speed in the context of Michelson-Morley experiment, using the key quantity or physical process before any example is added.
- is correct because it matches Discuss how the experiment supports constant light speed.
- through Michelson-Morley, special relativity, time dilation, de Broglie wavelength.
Explanation
Why this works
Stem being answered: Which statement gives the clearest definition needed for Discuss How The Experiment Supports Constant Light Speed? Route focus: turning-points-in-physics / Special Relativity.
Key vocabulary for this item: discuss, how, experiment, supports, constant, light, speed. Option check: keep Graph Reading answer 933d0d: A because it matches the stem; reject alternatives that change discuss, how, experiment 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.
