Column I Column II
(A) Intensity of light received by lens. (P) Radius of aperture(R).
(B) Angular magnification. (Q) Dispersion of lens.
(C) Length of telescope. (R) Focal length $f_0, f_e$.
(D) Sharpness of image. (S) Spherical aberration.
A
$$ [\mathrm{A} \rightarrow(\mathrm{P}) ; \mathrm{B} \rightarrow(\mathrm{R}) ; \mathrm{C} \rightarrow(\mathrm{R}) ; \mathrm{D} \rightarrow(\mathrm{P}, \mathrm{Q})]$$
B
$$ [\mathrm{A} \rightarrow(\mathrm{P}) ; \mathrm{B} \rightarrow(\mathrm{R}) ; \mathrm{C} \rightarrow(\mathrm{R}) ; \mathrm{D} \rightarrow(\mathrm{P}, \mathrm{Q}, \mathrm{~S})]$$
C
$$ [\mathrm{A} \rightarrow(\mathrm{R}) ; \mathrm{B} \rightarrow(\mathrm{P}) ; \mathrm{C} \rightarrow(\mathrm{R}) ; \mathrm{D} \rightarrow( \mathrm{Q}, \mathrm{~S})]$$
D
$$ [\mathrm{A} \rightarrow(\mathrm{P}) ; \mathrm{B} \rightarrow(\mathrm{R}) ; \mathrm{C} \rightarrow(\mathrm{S}) ; \mathrm{D} \rightarrow( \mathrm{Q})]$$
