How does the diameter of a telescope affect its observational quality?.
- A.A larger diameter allows for more light collection, improving image brightness.
- B.A smaller diameter reduces the amount of light collected, making images clearer.
- C.The diameter has no effect on the quality of the images produced.
- D.A larger diameter decreases the resolving power of the telescope.
Model answer
What a good answer should say
- A larger diameter allows for more light collection, improving image brightness.
Explanation
Why this works
A larger diameter increases the collecting power of a telescope, allowing it to gather more light, which enhances the brightness and clarity of the images observed.
