Ray Optics and Optical Instruments - Result Question 2
2. Match the corresponding entries of column-1 with column-2 (Where $m$ is the magnification produced by the mirror):
Column-1
(P) $m=-2$
(A) Convex mirror
(Q) $m=-\frac{1}{2}$
(B) Concave mirror [2016]
Column-2
(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: 2. (a)
Solution:
- (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
