Vedclass · Answer

(A) The magnifying power $(M)$ of an astronomical telescope is given by the formula $M = \frac{f_o}{f_e}$,where $f_o$ is the focal length of the objective lens and $f_e$ is the focal length of the eyepiece lens.To obtain a high magnifying power,the numerator $(f_o)$ must be large and the denominator $(f_e)$ must be small.Therefore,the objective should have a large focal length and the eyepiece should have a small focal length.

The magnifying power of a telescope is high if its objective and eyepiece have respectively
