PARALLAX BASELINE case: Which option best applies the AQA A-Level Physics objective "Use Wien's law to estimate surface temperature." in Temperature and black-body radiation using the relevant astronomical observation rather than a generic calculation?.
- A.astro-218-parallax-baseline: Use Use Wien's law to estimate surface temperature. in Temperature and black-body radiation.
- B.astro-218-parallax-baseline: Swap Temperature and black-body radiation with a different Classification of stars method.
- C.astro-218-parallax-baseline: Give a number or label without linking it to the astronomical evidence.
- D.astro-218-parallax-baseline: Ignore the observation and use a generic star or telescope statement.
Model answer
What a good answer should say
- The correct option is astro-218-parallax-baseline: Use Use Wien's law to estimate surface temperature.
- in Temperature and black-body radiation.
Explanation
Why this works
It is correct because the parallax baseline context supports use Wien's law to estimate surface temperature. 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.
