What is the definition of resolution in the context of measurements?.
- A.Resolution is the smallest change in a measured quantity that can be detected
- B.Resolution is the degree of closeness to the true value
- C.Resolution is the ability to repeat measurements consistently
- D.Resolution is the total uncertainty in a measurement
Model answer
What a good answer should say
- Resolution is the smallest change in a measured quantity that can be detected
Explanation
Why this works
Resolution is defined as the smallest change in a measured quantity that can be detected by a measuring instrument. The key difference is that resolution focuses on the instrument's capability to discern small changes, while accuracy relates to how close a measurement is to the true value.
Resolution is applicable when discussing the limits of measurement devices, while accuracy applies when evaluating measurement correctness. Therefore, the correct answer emphasizes the instrument's sensitivity to changes.
