What is a disadvantage of using a single large telescope compared to an array of smaller telescopes?.
- A.Higher cost for construction and maintenance
- B.Lower light-gathering power
- C.Increased diffraction effects
- D.Limited observational capabilities
Model answer
What a good answer should say
- Higher cost for construction and maintenance
Explanation
Why this works
Single large telescopes often require significant investment in construction and ongoing maintenance, making them more expensive compared to arrays of smaller telescopes, which can be built incrementally. While a single large telescope may provide high-quality images, the cost factor makes arrays a more viable option for many observatories.
