Question

In column-(I) some optical devices with type of object are given. Match them with column-II in which some characteristic of possible images are given :
$$\begin{array}{cc}\text{Column-I}& \text{Column-II}\\ \text{(A) Concave mirror, virtual object}& \text{(P) Real and enlarged image}\\ \text{(B) Convex mirror, virtual object}& \text{(Q) Virtual, enlarged image}\\ \text{(C) Convex lens, virtual object}& \text{(R) Real and Erect image}\\ \text{(D) Concave lens, real object}& \text{(S) Virtual and inverted image}\\ & \text{(T) Virtual and diminished image}\end{array}$$
Which of the following option has the correct combination considering column-I and column-II.

• A. D $\to$ P
• B. B $\to$ P, Q
• C. C $\to$ T
• D. A $\to$ R

Answer 1

The correct option is D A $\to$ R

A $\to$ R; B $\to$ P,Q,S; C $\to$ R; D $\to$ T
$u$ vs $v$ graph concave mirror
From region 4 Virtual object forms erect and real image.

$v$ vs $u$ graph convex mirror

From region 2 and 3
convex mirror can form both types of images; real and virtual (for virtual object)

Convex lens

Region 3 for virtial object image is real and erect.

Concave lens

For real object image is virtual and diminished.
