Solution
The inner surface of the reflector of a torch acts as a concave mirror.
Explanation:
The inner surface of the reflector in a torch is curved inward, like a concave mirror. This shape reflects and focuses light from the bulb into a narrow beam, making the light more directed and useful for illumination. A concave mirror converges light rays to a focal point, which is why it’s used in torches to focus the light.

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.
