Last updated: 6/13/2023

The convex surface of a thin concavo convex lens of glass of refractive index 1 5 has a radius of curvature 20 cm and the concave surface has radius of curvature 60 cm The lens is placed on the plane mirror as shown An object O is placed on the principal axis at distance x from the lens such that object O and image coincide After that water is filled in the lens such that the top surface becomes flat I O Then the object is again shifted by Ax such the object and image coincide again If then refractive index of water is 3 1 5 ci ad gada 3d da H 3AA AAG A 20 Ads Scal A60 cm Tefy uzaz anda 749 92 zu ga 1 yc de 2 SA UHR ZU GA fu such as da ga c 38 UHR HR Ga f eff zag anda s ud 1 A c r faz fa sa fc azg ay ufafara ya arudi s i uft va mi 4 3 B C 1 0 D l X x 30 cm nc Ax 10 cm x 60 cm Correct Answer Ax 15 cm Correct Answer
