Detailed explanation-1: -The main difference between the telescope and microscope is that the telescope is used to see the distant object with the help of magnification but the image is apparent but the microscope is used to see the small object with the help of magnification but the image is apparent.
Detailed explanation-2: -When the focal length of eyepiece decreases the magnification increases. We get a bigger and clearer image of the object viewed.
Detailed explanation-3: -Updated On: 27-06-2022 In a telescope, the difference in the focal lengths of two lenses is larger.
Detailed explanation-4: -3. In which of the following instruments, the objective has a large focal length and a very large eyepiece? Explanation: In telescopes, it is desired to provide angular magnification of distant objects.
Detailed explanation-5: -Assertion :The focal length of objective lens in telescope is much more than that of eye piece. Reason: Telescope has high resolving power due to large focal length.
