What is the main limitation of a telescope's resolving power?.
- A.The size of the objective lens
- B.Atmospheric turbulence
- C.The type of light being observed
- D.The quality of the eyepiece
Model answer
What a good answer should say
- Atmospheric turbulence
Explanation
Why this works
Atmospheric turbulence can distort the light coming from celestial objects, limiting the resolving power of ground-based telescopes. This effect can blur images and reduce clarity, making it difficult to distinguish fine details.
