Problems on Mirror Images
Mirror Image: A mirror image is a reflected duplication that appears identical but in reverse. The image of an object, as seen in a mirror, is called 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 Lateral Inversion.
The letters having identical mirror images are:
A, H, I, M, O, T, U, V, W, X, Y
Example: Mirror-Images of certain words are given below:
Answer: Suppose that a mirror M was kept to the right of the given figure as shown below:
Now, we know that
- The closer an object is from the mirror, the closer its image will be from the mirror and the farther an object is from the mirror the farther its image will be from the mirror. Therefore the image of the dot should be closer to the mirror than the image of the rectangle. That is :
- The image of a line which is inclined to the mirror is also inclined but the inclination of the image is inverted. Thus the two inclined lines will be inverted in their images as shown below:
