The left end of a long glass rod 6.00 cm in diameter has a convex hemispherical surface 3.00 cm in radius. The refractive index of the glass is 1.60. Determine the position of the image if an object is placed in air on the axis of the rod at the following distances to the left of the vertex of the curved end: (a) infinitely far,
(b) 12.0 cm;
(c) 2.00 cm.

Complete Question

The left end of a long glass rod 6.00 cm in diameter has a convex hemispherical surface 3.00 cm in radius. The refractive index of the glass is 1.60. Determine the position of the image if an object is placed in air on the axis of the rod at the following distances  1.00 cm  to the left of the vertex of the curved end:

(a) infinitely far,

(b) 12.0 cm;

(c) 2.00 cm.

The  image distance is  

Explanation:

From the question we are told  that

   The  diameter is  

   The radius of the convex hemisphere is  

    The  refractive index is

     The object distance is  

      The refractive index of air is
