Question
A refracting telescope has an angular magnification of 83.00. The length of the barrel is 1.500 m. What are the focal lengths of (a) the objective and (b) the eyepiece?
Step 1
This can be written as: \[|M| = \frac{Fo}{Fe}\] Given that the magnification is 83, we can write this as: \[83 = \frac{Fo}{Fe}\] From this, we can express Fo in terms of Fe: \[Fo = 83 \cdot Fe\] Show more…

A telescope is constructed from two lenses with focal lengths of 95.0 $\mathrm{cm}$ and $15.0 \mathrm{cm},$ the 95.0 -cm lens being used as the objective. Both the object being viewed and the final image are at infinity. (a) Find the angular magnification of the telescope. (b) Find the height of the image formed by the objective of a building 60.0 $\mathrm{m}$ tall and 3.00 $\mathrm{km}$ away. (c) What is the angular size of the final image as viewed by an eye very close to the eyepiece?
