Numerade Educator ### Problem 66 Easy Difficulty # A laboratory (astronomical) telescope is used to view a scale that is 300$\mathrm{cm}$from the objective, which has a focal length of$20.0 \mathrm{cm} ;$the eyepiece has a focal length of 2.00$\mathrm{cm} .$Calculate the angular magnification when the telescope is adjusted for minimum eyestrain. Note: The object is not at infinity, so the simple expression$m=f_{o} / f_{e}$is not sufficientlyaccurate for this problem. Also, assume small angles, so that tan$\theta \approx \theta\$
