Question:

Match List-I with List-II for convex lens (symbols have their usual meanings)

List-I Position of object

List-II Details of image

(A) at 2F

(I) m > 1, virtual

(B) at F

(II) m < 1, real

(C) between lens and F

(III) m = 1, real

(D) between $∞$ and 2F

(IV) m >> 1, real

Choose the correct answer from the options given below:

Options:

(A)-(IV), (B)-(III), (C)-(II), (D)-(I)

(A)-(III), (B)-(I), (C)-(IV), (D)-(II)

(A)-(III), (B)-(IV), (C)-(II), (D)-(I)

(A)-(III), (B)-(IV), (C)-(I), (D)-(II)

Correct Answer:

(A)-(III), (B)-(IV), (C)-(I), (D)-(II)

Explanation:

The correct answer is Option (3) → (A)-(III), (B)-(IV), (C)-(II), (D)-(I)

List-I Position of object

List-II Details of image

(A) at 2F

(III) m = 1, real

(B) at F

(IV) m >> 1, real

(C) between lens and F

(II) m < 1, real

(D) between $∞$ and 2F

(I) m > 1, virtual

 

(A) Object at 2F

Image forms at 2F on the other side,

$m = 1$, real and inverted

⇒ (III) $m = 1$, real

(B) Object at F

Rays after refraction become parallel,

Image forms at infinity, magnification $m \to \infty$

⇒ (IV) $m \gg 1$, real

(C) Object between lens and F

Image forms on the same side of lens,

Virtual, erect, magnified ($m > 1$)

⇒ (I) $m > 1$, virtual

(D) Object between $\infty$ and 2F

Image forms between F and 2F on the other side,

$m < 1$, real and inverted

⇒ (II) $m < 1$, real
