How does the aperture size of a telescope relate to its ability to resolve closely spaced objects?.
- A.Larger apertures can resolve closer objects
- B.Smaller apertures can resolve closer objects
- C.Aperture size has no effect on resolution
- D.Resolution is only dependent on the telescope's focal length
Model answer
What a good answer should say
- Larger apertures can resolve closer objects
Explanation
Why this works
The diffraction limit of a telescope is inversely proportional to the aperture size. Therefore, increasing the aperture allows the telescope to resolve objects that are closer together, enhancing observational capabilities.
