The answer is not 48.5 **Educational Content: Calculating Angular Magnification of a Telescope**You have a telescope with an 85 cm focal length objective. Recall that simple two-element telescopes invert the images of the objects viewed through them.- Focal Length of Objective (\(f_o\)) = 85 cm- Focal Length of Eyepiece (\(f_e\)) = 1.75 cm**Problem:** What is the angular magnification (\(M\)) of this telescope when equipped with a 1.75 cm focal length eyepiece?**Solution:**The angular magnification (\(M\)) of a telescope is given by the formula:\[ M = \frac{f_o}{f_e} \]Substituting the given values:\[ M = \frac{85 \, \text{cm}}{1.75 \, \text{cm}} \]**Calculation:**- Divide 85 by 1.75 to find the magnification.**Result:**The angular magnification of this telescope with the given eyepiece is the solution to the division.**Note:** Always ensure that measurements are in the same units before performing calculations.

Given: Focal Length of objective,fO=85cm=85×10-2mFocal Length of eyepiece,fE=1.75cm=1.75×10-2m The negative of the focal length of the objective lens divided by the focal length of the telescope's eyepiece equals angular magnification. The angular magnification of the telescope will increase as the focal length of the primary mirror increases.The expression of the angular magnification is: M=f0fE .... (1) Substitute the value in equation (1). M=85×10-2m1.75×10-2mM=48.57 The angular magnification is 48.57.
