A telescope has the following specifications fo = 990 mm and fc = 6.0 mm. Find the (a) the angular magnitication of the telescope and (b) draw a ray diagram, the length.
Use diagrams to describe how the following types of telescope collect light from a single point-
source at infinity, and form a focused image in the focal plane:

(ii) Newtonian reflector
(iii) catadioptric telescope.
A telescope with focal ratio f/10 and diameter D = 0.5 m has a CCD detector placed at its focal
plane. The CCD chip has dimensions 3 × 3 cm2
. Determine the size of the field of view that can
be imaged on the CCD detector in units of arcminutes × arcminutes, and state whether or not an
image of the full moon can be captured. Assume the angular diameter of the full moon is 30
arcminutes.
A camera lens used for taking close-up photographs has a focal length of 28.4 mm. The farthest it can be placed from the film is 24mm.
Part (a) What is the closest object that can be photographed in mm?
Part (b) What is the magnification of this closest object?
Part (c) What is the power of the lens?
