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 For You
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.
Examples:
Q1: 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 onthe 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.
Q2: 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.
We may also have some questions that are a combination of letters and numbers. Let us see the following.
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.
Q1: 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.
