Try this first
Airy disc limit: Choose the diffraction idea that limits telescope resolving power. This tests Explain how aperture affects diffraction-limited resolution. in Advantages of large diameter telescopes.
- A.Airy disc limit answer: The Airy disc sets a minimum angular separation for distinguishable images.
- B.Airy disc limit distractor: The stellar parallax angle vanishes.
- C.Airy disc limit misconception: The apparent magnitude scale becomes linear.
- D.Airy disc limit off-scope: The CMB temperature rises.
Model answer
What a good answer should say
- The correct option is Airy disc limit answer: The Airy disc sets a minimum angular separation for distinguishable images.
Explanation
Why this works
It is correct because it applies Advantages of large diameter telescopes evidence to Explain how aperture affects diffraction-limited resolution.. The other options are incorrect because they swap in a different astrophysics measurement, telescope property or cosmology idea.
