'Transit the telescope' of a theodolite involves
Show Hint
Think of transiting as flipping the telescope end-over-end in the vertical direction.

- \( \text{Rotating the theodolite about its vertical axis} \)
- \( \text{Rotating the telescope about its trunnion axis} \)
- \( \text{Rotating the telescope about its line of collimation} \)
- \( \text{Rotating the theodolite by 90 degrees in horizontal plane} \)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
'Transiting the telescope' of a theodolite refers to the operation of rotating the telescope about its horizontal axis, also known as the trunnion axis, through 180 degrees in the vertical plane. This allows for sighting in the reverse direction and is crucial for eliminating certain instrumental errors.
