Q. Angular magnification of an astronomical telescope in normal adjustment is

सामान्य समायोजन में एक खगोलीय दूरबीन का कोणीय आवर्धन होता है

fₒ/fₑ

fₑ/fₒ

fₒ - fₑ
एफₒ - एफₑ

fₒ + fₑ
एफₒ + एफₑ

In normal adjustment (final image at infinity), the angular magnification (M) of an astronomical telescope is given by:

M = \frac{f_{\text{objective}}}{f_{\text{eyepiece}}} = \frac{f_o}{f_e}
