Match the corresponding entries of column 1 with column 2. [Where m is the magnification produced by the mirror]

	Column 1		Column 2
(A)	$m = - 2$	(a)	Convex mirror
(B)	$m = - \frac{1}{2}$	(b)	Concave mirror
(C)	$m = + 2$	(c)	Real image
(D)	$m = + \frac{1}{2}$	(d)	Virtual image

Options:

Answer:

Solution:

$m = \frac{- V}{u} = \frac{f}{f - u}$

$m = - 2$ then "V" and "u" same given

$- 2 = \frac{f}{f - u} =- 2 f + 2 u = f$

$= 3 f = 2 u$

$\frac{+ 3 f}{2} = u$

For the concave mirror, f negative, u negative use same for all.
