TELESCOPE RESOLUTION case: Which option best applies the AQA A-Level Physics objective "Use inverse-square relationships for apparent brightness." in Classification by luminosity using the relevant astronomical observation rather than a generic calculation?.
- A.astro-225-telescope-resolution: Use Use inverse-square relationships for apparent brightness. in Classification by luminosity.
- B.astro-225-telescope-resolution: Swap Classification by luminosity with a different Classification of stars method.
- C.astro-225-telescope-resolution: Give a number or label without linking it to the astronomical evidence.
- D.astro-225-telescope-resolution: Ignore the observation and use a generic star or telescope statement.
Model answer
What a good answer should say
- The correct option is astro-225-telescope-resolution: Use Use inverse-square relationships for apparent brightness.
- in Classification by luminosity.
Explanation
Why this works
It is correct because the telescope resolution context supports use inverse-square relationships for apparent brightness. The distractors are weaker because they confuse observational evidence, distance scale, spectra, telescope resolution, brightness or cosmological reasoning with a nearby but different astrophysics idea.
