Find the angular magnification for the telescope


A telescope is constructed from two lenses with focal lengths of 90.0cm and 20.0cm , the 90.0?cm lens being used as the objective. Both the object being viewed and the final image are at infinity.

Find the angular magnification for the telescope.

M = -4.50 (CORRECT)

Find the height of the image formed by the objective of a building 60.0 m tall, 3.50km away.

|y?| = 1.54   cm   (CORRECT)

What is the angular size of the final image as viewed by an eye very close to the eyepiece?

?? =     _______ rad
