Vedclass · Answer

(D) In a reflecting telescope,a spherical mirror suffers from spherical aberration,which causes parallel rays incident on the mirror to focus at different points rather than a single point,resulting in a blurred image.By using a parabolic mirror,all parallel rays incident on the mirror are reflected to a single point (the focus) regardless of their distance from the principal axis.Therefore,the primary purpose of using a parabolic mirror is to eliminate spherical aberration and produce a sharp,clear image.
