What is one advantage of using a refracting telescope?.
- A.They can be built larger than reflecting telescopes.
- B.They provide clearer images of planets and stars.
- C.They are less expensive to manufacture.
- D.They do not require alignment.
Model answer
What a good answer should say
- They provide clearer images of planets and stars.
Explanation
Why this works
Refracting telescopes provide clearer images of planets and stars due to their design, which minimizes optical distortions. The lenses used in refracting telescopes can produce high-quality images with excellent contrast, making them ideal for planetary observation.
The key difference lies in the optical design: lenses focus light without the complications of mirror alignment. While they are limited in size compared to reflecting telescopes, their clarity in visible light makes them suitable for specific astronomical observations.
