Exam-style question
Try this first
Different wavelengths of light require different telescope designs because they interact with materials in unique ways. What is the primary reason for this necessity?.
- A.Different wavelengths have varying energy levels.
- B.Different wavelengths are absorbed differently by the atmosphere.
- C.Different wavelengths can be focused by lenses of different shapes.
- D.Different wavelengths travel at different speeds.
Model answer
What a good answer should say
- Different wavelengths are absorbed differently by the atmosphere.
Explanation
Why this works
Different wavelengths are absorbed differently by the atmosphere, which affects how much light reaches the telescope. This necessitates different designs to optimize light collection and minimize atmospheric interference, ultimately improving the quality of astronomical observations.
