How does the diameter of a telescope's aperture affect its resolving power?.
- A.Larger apertures decrease resolving power
- B.Larger apertures increase resolving power
- C.Aperture size has no effect on resolving power
- D.Resolving power is only affected by the eyepiece
Model answer
What a good answer should say
- Larger apertures increase resolving power
Explanation
Why this works
A larger aperture allows more light to enter the telescope, which improves the resolving power. This means that telescopes with larger diameters can distinguish finer details in astronomical images.
