Match List I with List II and select the correct answer using the codes given below the lists :

List I
(Position of the object)

List II
(Magnification)
(I) An object is placed at focus before a convex mirror (A) Magnification is - $\infty$
(II) An object is placed at centre of curvature before a concave mirror (B) Magnification is 0.5
(III) An object is placed at focus before a concave mirror (C) Magnification is +1
(IV) An object is placed at centre of curvature before a convex mirror (D) Magnification is – 1
(E) Magnification is 0.33

Moderate

Solution

$m = \frac{f}{f - u} (o r) m = \frac{- v}{u} 1) m = \frac{f}{f - (- f)} = \frac{1}{2} 2) m = \frac{- v}{u} = \frac{- (- 2 f)}{(- 2 f)} = - 1 3) m = \frac{f}{f - u} = m = \frac{- f}{- f - (- f)} = - \infty 4) m = \frac{f}{f - u} = m = \frac{f}{f - (- 2 f)} = \frac{1}{3} = 0.33$ .
