Answer the following questions:
(a) For the telescope described in Exercise (a)[A small telescope has an objective lens of focal length and an eyepiece of focal length . What is the magnifying power of the telescope for viewing distant objects when
(a) the telescope is in normal adjustment (i.e., when the final image is at infinity)?],
What is the separation between the objective lens and the eyepiece?
(b) If this telescope is used to view a tall tower away, what is the height of the image of the tower formed by the objective lens?

(a) an object placed between and of a concave mirror produces a real image beyond .
(b) a convex mirror always produces a virtual image independent of the location of the object.
(c) the virtual image produced by a convex mirror is always diished in size and is located between the focus and the pole.
(d) an object placed between the pole and focus of a concave mirror produces a virtual and enlarged image.
[Note: This exercise helps you deduce algebraically properties of images that one obtains from explicit ray diagrams.]
