GALAXY RECESSION case: Which option best applies the AQA A-Level Physics objective "Describe the function of objective and eyepiece lenses." in Astronomical telescope using two converging lenses using the relevant astronomical observation rather than a generic calculation?.
- A.astro-236-galaxy-recession: Use Describe the function of objective and eyepiece lenses. in Astronomical telescope using two converging lenses.
- B.astro-236-galaxy-recession: Swap Astronomical telescope using two converging lenses with a different Telescopes method.
- C.astro-236-galaxy-recession: Give a number or label without linking it to the astronomical evidence.
- D.astro-236-galaxy-recession: Ignore the observation and use a generic star or telescope statement.
Model answer
What a good answer should say
- The correct option is astro-236-galaxy-recession: Use Describe the function of objective and eyepiece lenses.
- in Astronomical telescope using two converging lenses.
Explanation
Why this works
It is correct because the galaxy recession context supports describe the function of objective and eyepiece lenses. 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.
