Mirror Images 4

Introduction
I. Mirror Images of Capital Letters
In this category questions are based on the criteria that a few figures
A A N N
are given and you have to find out which one is the exact image of the
given figure in a mirror placed in front of it. This image formation is B B O O
based on the principle of 'lateral inversion' which implies that size of C C P P
the image is equal to the size of the object but both sides are D D Q Q
interchanged. The left portion of the object is seen on the right side E E R R
and right portion of the object is seen on the left side. For example, F F S S
mirror image of ABC = ABC
G G T T
Note: There are '11' letters in English Alphabet which have
H H U U
identical mirror images: A, H, I, M, O, T, U, V, W, X, Y.
I I V V
Characteristics of Reflection by plane mirror
J J W W
1. Perpendicular distance of object from mirror = Perpendicular
K K X X
distance of image from mirror.
L L Y Y
2. The image is laterally inverted.
M M Z Z
II. Mirror Images of Small Letters

B A A 1 B 1 a a n n
b b o o
c c p p

B B 1 d d q q
C C 1
e e r r
f f s s
A A 1 g g t t

3. The line joining the object point with its image is normal to the h h u u
reflecting surface. i i v v
4. The size of the image is the same as that of the object. j j w w
k k x x
Example 1. Mirror-images of certain words are given below:
l l y y
(a) F U N :
m m z z
(b) G O L K O N D A :
Example 2. Mirror-images of certain combinations of alphabets III. Mirror Images of Numbers
and numbers are given below : 0 0 6 6

(a) BMC49JN2317 : BMC49JN2317 1 1 7 7
2 2 8 8
(b) 15bg82XQh : 15bg82XQh
3 3 9 9
