When is it more beneficial to use telescope arrays instead of a single large telescope?.
- A.When observing bright objects
- B.When high resolution is required
- C.When budget constraints are minimal
- D.When simplicity in design is preferred
Model answer
What a good answer should say
- When high resolution is required
Explanation
Why this works
Telescope arrays are particularly beneficial when high resolution is needed, as they can combine the light from multiple telescopes to create interference patterns that enhance detail. In contrast, a single large telescope may not achieve the same level of resolution due to its fixed aperture.
Thus, for detailed observations, arrays are more effective.
