16. Match the corresponding entries of column-1 with column-2 (Where $m$ is the magnification produced by the mirror):

[2016]

Column-1 Column-2
(P) $m=-2$ (A) Convex mirror
(Q) $m=-\frac{1}{2}$ (B) Concave mirror
(R) $m=+2$ (C) Realimage
(S) $m=+\frac{1}{2}$ (D) Virtual image

(a) $P \to B$ and $C, Q \to B$ and $C, R \to B$ and $D$, $S \to A$ and $D$.

(b) $P \to A$ and $C, Q \to A$ and $D, R \to A$ and $B$, $S \to C$ and $D$

(c) $P \to A$ and $D, Q \to B$ and $C, R \to B$ and $D$, $S \to B$ and $C$

(d) $P \to$ C and $D, Q \to B$ and $D, R \to B$ and $C$, $S \to A$ and $D$

Show Answer

Answer:

Correct Answer: 16.(a)

Solution:

  1. (a) Magnitude $m=+ve \Rightarrow$ virtual image

$m=-ve \Rightarrow$ real image

magnitude of magnification,

$|m|>1 \Rightarrow$ magnified image

$|m|<1 \Rightarrow$ diminished image
