Hi, I need some assistance answering the following questions. I am having some difficulty understanding the concepts.
(a) How large is the exit pupil of a 7-power telescope having an objective lens 50 mm in diameter?
(b) If the objective lens is 6 inches in focal length, what must be the focal length of the ocular?
(c) What focal length ocular should be used with this objective lens in order to produce a telescope having normal magnification for daytime use?
Dear student, please refer to the attachment for the solutions. Thank ...
The expert determines the objective lens length and focal length.
