Match Column I with Column II.
Column I - Column II
(i) Ray through centre of curvature - (A) Reflected parallel to principal axis
(ii) Ray through focus - (B) Converge at focus
(iii) Rays from infinite distance - (C) Emerge through focus
(iv) Refracted rays to infinity - (D) Retracing in mirrors

(i) → (D),
(ii) → (A),
(iii) → (B),
(iv) → (C)
Explanation:
(i) → (D): For this ray Zi = Zr = 0
(ii) → (A): The ray of light passing through the focus will emerge parallel to the principal axis after reflection.
(iii) → (B): When object is at infinity, the image is formed at the focus of a concave mirror.
(iv) → (C): A ray from the object parallel to principal axis will pars through the principal . focus after refraction in a convex lens.
