Question

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	(i)	Convex mirror
(b)	$m = - \frac{1}{2}$	(ii)	Concave mirror
(c)	$m = + 2$	(iii)	Real image
(d)	$m = + \frac{1}{2}$	(iv)	Virtual image

• A. A $\to$ a and c; B $\to$ a and d; C $\to$ a and b; D $\to$ c and d
• B. A $\to$ a and d; B $\to$ b and c; C $\to$ b and d; D $\to$ b and c
• C. A $\to$ c and d; B $\to$ b and d; C $\to$ b and c; D $\to$ a and d
• D. A $\to$ b and c; B $\to$ b and c; C $\to$ b and d; D $\to$ a and d

Answer 1

Answer: (D)

m = +ve $\Rightarrow $ virtual image
m = -ve $\Rightarrow $ real image
|m| > 1 $\Rightarrow $ magnified image
|m| < 1 $\Rightarrow $ diminished image
