Model answer
What a good answer should say
- Reflecting telescopes.
Explanation
Why this works
Reflecting telescopes are generally more suitable for large-scale astronomical surveys due to their ability to be constructed with larger apertures without the limitations of lens size and weight. The key difference is that mirrors can be made larger and are easier to support than large lenses, allowing for greater light-gathering power and improved resolution.
This makes reflecting telescopes ideal for deep-sky observations and capturing faint objects in the universe, which is essential for extensive astronomical surveys.
