Objective Lens


<div class="wp-block-create-block-problemblock">A telescope is constructed with two lenses separated by 25 cm.  The focal length of the objective is 20 cm.  The focal length of the eyepiece is 5.0 cm.  If an object is 100 m away from the objective lens, where is the final image of the eyepiece?  What is its magnification?</div>
