Question

what happens to the ray that along the principal axis or moves through the centre of curvature​

Answer 1

Answer:

Explanation:

Rule 2: When a ray of light passes through the centre of curvature, it gets reflected back along the same path. Rule 3: When a ray of light passes through the focus, it becomes parallel to the principal axis after reflection.

Answer 2

Answer:

according to Snell law the ray which move along the normal drawn to the surface does not deviate hence both rays in the given condition travel along normal,so they do not deviate
