Vedclass · Answer

(B) In a telescope,the focal length of the objective lens $(f_o)$ is much larger than the focal length of the eye lens $(f_e)$,i.e.,$f_o >> f_e$. In a microscope,the focal length of the objective lens $(f_o)$ is very small,and it is smaller than the focal length of the eye lens $(f_e)$,i.e.,$f_o Therefore,the relative difference between the focal lengths of the objective and the eye lens is significantly greater in a telescope compared to a microscope.

The relative difference between the focal lengths of the objective and the eye lens in a microscope and a telescope is given as:
