0In the figure shown a point object O is placed in air on the principal axis. The radius of curvature of the spherical surface is 60 cm. If is the final image formed after all the refractions and reflections.
(A) If d_1=120 cm, then the ' f_f ' is formed on ' O ' for any value of d_2.
(B) If d_1=240 cm, then the 'If' is formed on ' O ' only if d_2=360 cm.
(C) If d_1=240 cm, then the 'I If' is formed on ' O ' for all values of d_2.
(D) If d_1=240 cm, then the 'If' cannot be formed on ' O '.
