The correct Answer is:
To solve the problem step by step, we need to analyze the behavior of the different types of mirrors and how they affect the size of the images produced. ### Step-by-Step Solution: 1. **Understanding the Problem**: - The child sees her head bigger, the middle portion of her body the same size, and her legs smaller. This indicates that different parts of her body are being reflected differently by the mirror. 2. **Identifying the Type of Mirror for Each Part**: - **Head (Bigger Image)**: A concave mirror can produce a magnified image when the object is placed close to the mirror. Thus, the head is likely being reflected by a concave mirror. - **Middle Portion (Same Size)**: A plane mirror produces an image of the same size as the object. Therefore, the middle portion of the body is likely being reflected by a plane mirror. - **Legs (Smaller Image)**: A convex mirror always produces a diminished (smaller) virtual image. Hence, the legs are likely being reflected by a convex mirror. 3. **Combining the Mirrors**: - Based on the observations: - The **concave mirror** is used for the head (producing a larger image). - The **plane mirror** is used for the middle portion (producing the same size image). - The **convex mirror** is used for the legs (producing a smaller image). - Therefore, the order of the mirrors from top to bottom is: **Concave, Plane, Convex**. 4. **Conclusion**: - The correct order of the combination of mirrors is **Concave Mirror, Plane Mirror, Convex Mirror**. ### Final Answer: The order of combinations for the magic mirror from the top is: **Concave, Plane, Convex**.

State the following statements as TRUE or FALSE. a. A convex mirror cannot from a real image for a real object. b. The image formed by a convex mirror is always diminished and erect. c. Virtual image formed by a concave mirror is always enlarged. d. Only in the case of a concave mirror, it may happen that the object and its image move in same direction. e. In the case of a concave mirror, the image always move faster than the object. f. If an object is placed in front of a diverging mirror at a distance equal to its focal length, then the height of image formed is half of the height of object. g. For two positions of an object , a concave mirror can form englarged image. h. Concave mirror is used as a rear view mirror in motor vehicles. i.

A man of height H is standing in front of an inclined plane mirror at an angle theta from horizontal. The vertical separation between man and inclined plane is x. Man can see its complete image in length (H(H+x)"sin"theta)/(H +2x) of mirror . (Given : x = H = 1m and theta = 45^(@) ) If man starts moving with velocity 1 ms^(-1) horizontally, find out length of mirror at t=1s in which he can see his complete image.
