Question
You are given three mirrors of different types. How will you identify each one of them?
Solution
We are given three different types of mirrors. To identify each one of them we will take an object and place it in different positions. Accordingly, we will get the positions of the image and nature of the image for each mirror, through which mirrors can be identified.
| Properties of the image formed | Plane mirror | Concave mirror | Convex mirror |
| Real or virtual | Virtual | Real except when the object is near the mirror | Virtual |
| Erector inverted | Always erect | Inverted when real and erect when virtual | Always erect |
| Size of image | Image formed is of the same size as the object | Diminished for certain positions and enlarged for others | Always diminished |

Role play
Here is a game that a group of children can play. One child will be chosen to act as object and another will act as the image of the object. The object and the image will sit opposite to each other. The object will make movements, such as raising a hand, touching an ear etc. The image will have to make the correct movement following the movement of the object. The rest of the group will watch the movements of the image. If the image fails to make the correct movement, she/he will be retired. Another child will take her/his place and the game will continue. A scoring scheme can be introduced. The group that scores the maximum will be declared the winner.
