Physics - Geometrical Optics Question with Solution | TestHub
Column-I shows O₁ (object) and O₂ (image). The optical system responsible can be a spherical mirror, plane mirror or a thin lens. In the case of the lens and spherical mirror, the straight line shows the principal axis. Match column-I and column-II.
Column-I
(A) 
(B) 
(C) 
(D) 
Column-II
(P) Concave mirror 
between O₁ and O₂
(Q) Diverging lens between O₁ and O₂
(R) Convex mirror 
between O₁ and O₂
(S) Converging lens between O₁ and O₂
(T) Inclined plane mirror somewhere between O₁ and O₂.
Options:
Answer:
Solution:
(A) and (B): O₁ and O₂ lie on the same side of the principal axis (erect image), matched by a convex mirror (always erect, virtual image) or a suitably inclined plane mirror placed between O₁ and O₂: A → R, T and B → R, T.
(C) and (D): O₁ and O₂ lie on opposite sides of the principal axis (inverted image), matched by a diverging lens, a converging lens between O₁ and O₂, or an inclined plane mirror: C → Q, S, T and D → Q, S, T.
A concave mirror (P) is not consistent with any of the four arrangements. Hence option (A).
