Question

To have the highest magnification in a telescope, the focal length of the objective lens should be _________ and the focal length of the eyepiece lens should be ________. To have the highest magnification in a telescope, the focal length of the objective lens should be _________ and the focal length of the eyepiece lens should be ________.

Answer 1

Answer:

the focal length of the objective lens is GREATER and the focal length of the eyepiece must be LOWER

Explanation:

The telescope is one of the most used optical instruments, allows you to see objects that are at great distances, for this two lenses are combined that is close to the eye and the other objective.

When the magnification for a far vision point is resolved, the expression is found

.m = - fo / faith

Where m is the magnification, fo and faith are the focal distances of the objective and the eyepiece, the sign indicates that the image is inverted

For this amount to be maximum, the focal length of the objective lens is GREATER and the focal length of the eyepiece must be LOWER
