$$Parallel rays fall on a thin lens whose radii of curvature are R$1=15$cm $$and

$$R$2=10\mathrm{.}0$cm $$If the lens has a refractive index of $1\mathrm{.}52,$a diameter of $5\mathrm{.}00$cm$,$and its longitudinal spherical aberration is $8\mathrm{.}04$x$10-3$cm$,$find the value of the transverse spherical aberration.
