Exam-style question
Try this first
Explain when telescope arrays are preferred over single large telescopes and vice versa.
Model answer
What a good answer should say
- Telescope arrays are preferred when high resolution and sensitivity are required, especially for observing faint or distant objects, as they can combine signals to enhance image quality.
- Single large telescopes are favored for their simplicity and ability to gather more light in a single observation, making them suitable for bright objects or when budget constraints limit the number of telescopes.
Explanation
Why this works
This question assesses the ability to apply knowledge of telescope types to specific observational scenarios. By explaining the conditions under which each type is advantageous, students show a deeper understanding of practical applications in astronomy.
