What of the following statements is true for reflecting telescopes?
- The main focusing optical piece is a mirror
- It is rarely used by professional astronomers
- The main focusing optical piece is a lense
- It is usually a very long tubular telescope.
Homework Answers
Ans.
Since reflecting telescopes have short tube, option (D) is incorrect. here, we use mirror instead of lens and hence option C is also incorrect. Hence the correct option is (A)
I hope the answer is clear to you, in case you have any query, please leave a comment, we will try our best to fix it. If you are satisfied with the answer, leave a thumbs up, your support is valuable. Thank You

ASTRONOMY (Ranking Reflecting Telescopes and Light Collection )
Part A Listed following are the names and mirror diameters for six of the world’s greatest reflecting telescopes used to gather visible light. Rank the telescopes from left to right based on their light-collecting area from largest to smallest. For telescopes with more than one mirror, rank-based on the combined light-collecting area of the mirrors.Part B Shown following are the primary mirror arrangements and total light-collecting area of five different telescopes. Each mirror uses a different segmented arrangement, but assume that they...
