Question

Match Column I with Column II.

Column I
(i) Ray through centre of curvature
(ii) Ray through focus
(iii) Rays from infinite distance
(iv) Refracted rays to infinity

Column II
(A) Reflected parallel to principal axis
(B) Converge at focus
(C) Emerge through focus
(D) Retracing in mirrors​

Answer 1

Answer:

(i) - (D), (ii) - (A),  (iii) - (B), (iv) - (D)

Explanation:

(i) Ray through centre of curvature retrace in mirrors

(ii) Ray through focus reflects back parallel to principal axis in mirrors  

(iii) Rays from infinite distance converge at principal focus

(iv) Refracted rays to infinity emerge through principal focus

 

Answer 2

Answer:

(i) → (D),

(ii) → (A),

(iii) → (B),

(iv) → (C)

Explanation:

(i) → (D),

(ii) → (A),

(iii) → (B),

(iv) → (C)

(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 the object is at infinity, the image is formed at the focus of a concave mirror.

(iv) → (C): A ray from the object parallel to the principal axis will par through the principal. focus after refraction in a convex lens.
