Input interpretation
telescope magnifying power
Equation
M = f_o/f_e | M | subject magnification factor f_e | eyepiece focal length f_o | objective focal length
Input values
eyepiece focal length | 26 mm (millimeters) objective focal length | 2000 mm (millimeters)
Results
subject magnification factor | 76.92
Possible intermediate steps
Calculate the subject magnification factor using the following information: known variables | | f_e | eyepiece focal length | 26 mm f_o | objective focal length | 2000 mm The relevant equation that relates subject magnification factor (M), eyepiece focal length (f_e), and objective focal length (f_o) is: M = f_o/f_e Substitute known variables into the equation: known variables | | f_e | eyepiece focal length | 26 mm f_o | objective focal length | 2000 mm | : M = (2000 mm)/(26 mm) Cancel the units in (2000 mm)/(26 mm): M = 2000/26 Evaluate 2000/26: Answer: | | M = 76.92
