What is a key advantage of using telescope arrays compared to a single large telescope?.
- A.Increased light-gathering power
- B.Improved resolution through interference
- C.Simpler design and construction
- D.Lower cost of individual telescopes
Model answer
What a good answer should say
- Improved resolution through interference
Explanation
Why this works
Telescope arrays consist of multiple smaller telescopes working together, which can enhance resolution through interference patterns. In contrast, a single large telescope has a fixed aperture size.
Arrays are particularly useful when observing fine details in astronomical objects, while single telescopes are limited by their size. Therefore, telescope arrays are preferred for high-resolution observations.
