364534 Assertion :
A reflecting type telescope is preferred in astronomy.
Reason :
Weight of the mirrors are less as compared to the lenses.

364535 The magnification produced by an astronomical telescope for normal adjustment is 10 and the length of the telescope is \(1.1\;m\). The magnification when the image is formed at half distance of the distinct vision (\(D = 25\,cm\)) is

364536 A telescope has an objective of focal length \(50\;cm\) and an eyepiece of focal length \(5\,cm\). The least distance of distinct vision is 25. The telescope is focussed for distinct vision on a scale \(200\,cm\) away. The separation between the objective and the eyepiece is

364537 While viewing a distant object with telescope a housefly sits on objective lens. Then
