Introduction

Mirror Image or horizontal Plane and water image are two new subjects or parts in non-verbal reasoning, Mirror image is also known as horizontal plane so we are going to learn mirror image methods and Watter images .

How to solve mirror image questions easily and little tricks and shortcuts of mirror image or horizontal plane of non verbal reasoning.
Have you ever see Your face in mirror ? basically in mirror right hand becomes left and left hand becomes right, right ? and your head seems to be same as you thinking right? so that’s the trick in mirror image right part of contents appears on left side and left part of contents appears right side but the top upper level and down lower level remains same. 

Water Images

The reflection of an object into the water is its water image. It appears by inverting an object vertically i.e. upside down. The water image of the figure looks like the mirror image of the figure in case the mirror is horizontally at the bottom of the figure.

From the above figure, it is clear that the water image is inverted from a real a real image in which the L H S and the R H S remain at their position i.e. remains on the same side as they are in original figure but the top and bottom of the figure gets interchanged i.e. top becomes bottom and the bottom becomes the top.

In the following section we will extensively be using these two rules.

• The letters which have the same water images are – C, D, E, H, I, K, O, X.
• The small letters which have the same water images after reflection on the surface of a water body are c, l, o, x.

Solved Examples

Directions: In each of the following questions, a word/group or numbers or both are followed by four alternatives (a), (b), (c), (d) showing possible water image of that word/group of letters or numbers or both. One, out of these four alternatives, is the exact water image of that word/group of letters or numbers or both. Choose from the alternatives the correct water image of that word/group of letters or numbers or both.

Before solving the questions remember there are two main things that you need to keep in mind:

A) The L H S and the R H S remain at their position i.e. remains on the same side as they are in the original figure.

Question 1: From the following choose the alternative that correctly represents the water image of the word N U C L E A R .

A) 1
B) 2
C) 3
D) 4
E) None of these

Answer: One of the most common mistakes that people make while answering the questions on water images is to confuse these questions with that of the mirror images. Remember in case of a water image the L H S and the R H S remain at their position i.e. remains on the same side as they are in the original figure but the top and bottom of the figure get interchanged i.e. top becomes bottom and the bottom becomes the top.
Keeping this in mind, the first image should be the water image of the letter N and the last image should be a water image of the letter R. So option (1) is wrong.
A shortcut to solving these questions is to locate letters that are familiar to you and whose water images are easier for you to imagine. Suppose that letter is L, then you will see that out of the remaining three options the correct answer is either (3) or (4) as in (2) the water image of L is not correct. Now if you focus on the options (3) and (4), you will see that the water image of E is not correct in (3) and hence the correct option is D) 4.

Question 2: Choose the option that represents the correct mirror image of b r i d g e

A) 1
B) 2
C) 3
D) 4
E) None of these

Answer: Let us recall the two rules that we have. Rule A) states that the L H S and the R H S remain at their position i.e. remains on the same side as they are in the original figure. Well, that doesn’t help as all the options seem to be correct. Thus we  consider rule B) the top and bottom of the figure gets interchanged i.e. top becomes bottom and the bottom becomes the top. Taking these two into consideration, we see that the correct option here is B) 2.

Miscellaneous Examples ( Mixed Letters and Numbers)

Directions: In each of the following questions, a combination of letters and numbers is followed by four other combinations of letters and numbers showing the possible water images of the letter-number combo. Choose the correct water image of the four options.
Question 1: G R 9 8 A P 7 6 E S

A) 1
B) 2
C) 3
D) 4
E) None of these

Answer: Using the two rules that we have, we can say that the answer to the above question is C) 3.

Mirror Images

The image of an object as seen in a mirror is its mirror reflection or mirror image. In such an image, the right side of the object appears on the left side and vice versa. A mirror-image is therefore said to be laterally inverted and the phenomenon is called the lateral inversion.

Some letters don’t change upon reflection. In other words, they are the same as that of their Mirror Images. The letters having identical mirror images are A, H, I, M, O, T, U, V, W, X, Y. Similarly, in small letters we have i, l, o, v, w, and x that have the same Mirror Image as that of their original images. The number 1 and 8 are the only two numbers with their identical mirror images.

Any object that has a bilateral symmetry will have its mirror image the same as that of the object. By that, we mean that if you were to draw a line from top to bottom that splits the object into two parts, such that both the parts can be superimposed onto each other, the object’s Mirror Image will be same as that of the object’s image.

Working Rule For Mirror Images

Let us consider an example below.
From the above figure, it is clear that in a mirror top and bottom of an image doesn’t change but the Left Hand Side (L H S) of real image becomes the Right Hand Side (R H S) in mirror image and the R H S in the real image becomes the L H S in the mirror image.

There are basically two types of questions in this section. The first kind is the letter/ Number Images. Here, you will have a combination of letters/words/numbers. We have to find their mirror images out of given alternatives. The second is the Geometrical Images questions. In this type of questions, we deal with figures having defined geometrical shapes.Let us see some solved examples to understand the concept better.

Solved Examples

Directions: In each of the following questions, four alternatives are given, which follow the word or number marked as a question. You have to select one alternative, which exactly matches with the mirror of the word/ number in the question.

Question 1: Which among the following illustrations specifies the correct mirror image of O B S T I N A T E ?

Answer: The first step is to check the first and the last letters. We know that the reflection at a mirror is equivalent to an inversion. In other words, we say that in a mirror top and bottom of an image doesn’t change but the Left Hand Side (L H S) of real image becomes the Right Hand Side (R H S) in mirror image and the R H S in the real image becomes the L H S in the mirror image.
A time-saving trick is to eliminate the letters whose mirror image is the same as that of the original shape. The first letter in the mirror image of O B S T I N A T E should be the mirror image of E which is only in the option (a). Therefore the correct option is (a).

Question 2: Which among the following illustrations specifies the correct mirror image of P R O C R A S T I N A T E ?

Answer: Let us see the first letter in the mirror image of P R O C R A S T I N A T E. The first letter in the mirror image would be the last letter in the original word P R O C R A S T I N A T E, which is E. The only option that has its first letter as the mirror image of E is option (b). Therefore (b) is the correct option.
