Q3
A small object A is placed on the principal axis of an equiconvex lens at a distance of 30 cm. The refractive index of the glass of the lens is 1.5 and its surfaces have radius of curvature, R=20 cm. Two glass slabs S1 and S2 have been placed behind the lens as shown. Thickness of the two slabs are 6 cm and 4 cm respectively & refractive indices are 32 and 2 respectively.
