A point object is places on the principal axis of a thin lens with parallel curved boundaries, i.e., having same radii of curvature. Discuss about the position of the image formed.

Explanation

`(1)/(f) = (n_("net") - 1) ((1)/(R_(1)) - (1)/(R_(2))) = 0, [:' R_(1) = R_(2)]`
`(1)/(v) - (1)/(u) = 0` or `v = u` i.e., rays pass without appreciable bending.
