For Electron microscopes, which option best applies turning-point evidence to Link shorter de Broglie wavelength to improved resolution.?.
- A.Use the mass-energy equivalence: energy change is linked to mass change, not chemical energy, so the answer tests relativistic energy.
- B.Use a classical formula label without connecting it to the experimental evidence.
- C.Describe the apparatus only and omit the physical conclusion drawn from the result.
- D.Treat the effect as ordinary circuit behaviour rather than a turning-point physics idea.
Model answer
What a good answer should say
- The correct option is Use the mass-energy equivalence: energy change is linked to mass change, not chemical energy, so the answer tests relativistic energy.
Explanation
Why this works
It is correct because it links the named experiment or model change to the physical evidence and conclusion. The other options are incorrect because they quote a formula without interpretation, describe apparatus without the conclusion, or reduce the turning-point idea to ordinary circuit or force behaviour.
