Question

When a ray is travelling from a rarer to dencer medium parallel to principal axis then
​

Answer 1

Explanation:

Principal axis is the imaginary line which passes through pole and center of curvature of the curved surface. When a ray parallel to principal axis travelling from rarer to denser medium strikes convex surface, it gets refracted and bends towards the normal.
