Questions Based on Mirror Images

In this article, we will learn about Letter/Number Images, Geometrical Images, Letter/Number Images and more.

Table of Content
  •  

A mirror image is a picture generated by placing a mirror in front of real image, or we may say that the reflection of an item into the mirror is termed its mirror image. There are two sorts of mirror image questions that are commonly posed in tests. There are two types of images: letter/number images & geometrical images. The question in Letter/ Number Images will be presented using a combination of the letters/words/numbers. Users must select their mirror pictures from a set of possibilities. Geometrical Images are figures with specified geometrical shapes.

Mirror Images

A mirror image or mirror reflection is the image of a body as viewed in a mirror. Right side of the body appear on the Left side of the body in such an image, and vice versa. As a result, a mirror-image is said to be laterally inverted, and the phenomenon is known as lateral inversion.

Some letters do not alter when reflected about which means that they are identical to their Mirror Images. A, H, I, M, O, T, U, V, W, X, Y are the letters with identical mirror images. Similarly, we have I l, o, v, w, and x in little letters that have same mirror image as their original images.

Objects with Different Mirror Image

Mirror image of a figure is usually different from the actual image due to differences in the left and right sides of the figure. 

Objects with Same Mirror Image

It is not uncommon for the mirror image to be similar to the actual figure. This is the case where the figure’s LHS and RHS halves are similar but in opposing directions. 

Types of Questions Based on Mirror Images

Based on the Horizontal Mirror

In such cases, a horizontal mirror is put at the bottom or top of the item, and the resulting image is similar to a water image. LHS & RHS remain constant in this sort of query.

Case 1: When mirror is placed horizontally at the bottom of object

Case 2: When mirror is placed horizontally at the top of object

Based on the Vertical Mirror

In such cases, a vertical mirror is positioned to the left or to the right of the object, and a common type of mirror image is generated in which the Left Hand Side (LHS) & the Right Hand Side (RHS) of the object swap positions while the top & bottom stay intact.

Case 1: When mirror is placed vertically right of the object

Case 2: When mirror is placed vertically left of the object

Letter/Number Images

In this sort of question, a number, letter, or a combination of the letters or numbers is provided, and applicants must discover their mirror images among the provided possibilities.

Mirror Image of the Clocks

In this sort of question, a candidate must determine the original locations of a clock’s hour & minute hands from positions of the hour and minute hands as viewed in a mirror. We must determine the true time in the clock using the time displayed by the mirror image of the clock.

Unless otherwise mentioned, the mirror is always retained in standard form, i.e., vertically, to produce the mirror image in the case of words, letters, and timepieces.

Conclusion

The reflection of a body in a mirror is referred to as its Mirror image. The top and bottom of image remain constant in mirror images, while the left and right sides of the image alternate.

In this article, we discussed the different types of questions based on mirror images.

The concept of mirror images is related to nonverbal thinking. In this topic, you will be given a genuine image as well as mirror images, and you must identify the correct mirror image.

A mirror-reflected clock shows quarter past three. What is the right time as displayed by the clock?

Which of the following is the correct mirror image of the word OBSTINATE ?

...Read full

(A) 9 : 45    (B) 8 : 15    (C) 8 : 45    (D) 9 : 15

ANSWER . Option (C) is the right answer.

Fix. (X) clearly shows that when viewed through a mirror, the time reported by the clock is 3.15. When the mirror is positioned vertically at AB, Fig. (Y) displays the current time in the clock, i.e. (8 : 45).

Answer. The right answer option (C).

Answer. Option (D) is the right answer.

The mirror is positioned horizontally at AB, i.e. at the bottom of question figure. As a result, only the figure (c) from the answer figure resembles the question figure’s water image. It signifies that option (c) is vertically inverted form of the question figure in which the top and bottom swap places while the LHS and RHS remain the same.

Answer. Option (B) is the correct answer to this problem.

The mirror is positioned vertically on the RHS of the question figure in this case. As a result, only the figure in answer figure (b) is the right mirror image.

Answer. The 1st step is to look through the first and last letters. We know that a reflection in a mirror is the same as an inversion. The top and bottom of an image do not change in a mirror, but Left Hand Side (L H S) of the real picture becomes the Right Hand Side (RHS) in the mirror image, and also the RHS of real image becomes the LHS in the mirror image.

A time-saving technique is to remove letters whose the mirror image is same as the original shape. The first letter in the mirrored image of O B S T I N A T E should be E.

Hence, option (A) is the correct answer.

What is Posterior Probability

A posterior probability, in Bayesian records, is the revised or updated probability of an event happening after taking into account new records. The posterior probability is calculated by updating the prior probability by using Bayes’ theorem. In statistical phrases, the posterior probability is the probability of event A taking place given that event B has taken place.
