Mirror/Water Image

 

 

 

OBJETIVES

         

·         Students will learn how different objects are seen when they get reflected both in mirror and in Water.

    

 

 

INTODUCTION

 

The reflection of object into the mirror is called its mirror image. It is obtained by inverting an object laterally. If we combine the original figure and mirror image together they form symmetry.

 

 

 

MIRROR IMAGES

 

 

Mirror Images of Capital letters

 

 

·         The capital letters which have the same mirror images are:

A, H, I, M, 0, T, U, V, W, X, Y

 

 

 

 

Mirror Images of Small letters

 

        

 

·         The small letters which have the same mirror images are:

                        i, l, o, v, w, x

 

 

 

Mirror Images of Numbers

 

·      0 and 8 numbers have the same mirror images.

 

 

Mirror Image of Clock Time

For mirror image of clock time, the given time shall be subtracted from 12 00 or 11.60.

 

 

Example 1:

 

What will be the mirror image of clock time 3:40?

Explanation:

By using simple trick

               

 

 

 

 

WATER IMAGE

 

 

INTRODUCTION

 

 

The reflection of an object into the water is called its water image It is obtained by inverting an object vertically.

 

 

 

 

Technical Definition

 

In water image (horizontal), the LOWER and UPPER parts interchange positions and the LEFT and RIGHT parts remain constant.

 

Water Images of Capital Letters

 

 

 

Water Images of Small Letters

 

 

 

 

Water Images of Numbers

 

 

 

Water Images of Clock Time

For water image of clock time, the given time shall be subtracted from 18 : 30.

 

 

Example 2:

What will be the water image of clock time 4 : 20?

Explanation:

By using simple trick

    

 

 

 

Point to be Remembered

 

There is a short trick which can be applied while doing this exercise.

·      Certain alphabets in capital form have the mirror image as well as the water image the same.

They are

            H      I       0      X

·      Some alphabets have similar water reflection i.e.

            C      D      E      H      I       O  X

·         Two number 0 and 8 have their water images exactly the same.

·         The mirror image of number 6 is the same as the water image of number 9.
