The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Mirrors**: There are different types of mirrors, including plane mirrors, concave mirrors, and convex mirrors. Each type has different properties regarding image formation. 2. **Identifying the Type of Mirror**: The question asks about a mirror that forms an image of the same size as the object. We need to identify which type of mirror has this property. 3. **Properties of a Plane Mirror**: A plane mirror is a flat mirror. One of its key properties is that it produces images that are virtual, upright, and of the same size as the object. 4. **Distance Relationships**: In a plane mirror, the distance of the object from the mirror (denoted as 'u') is equal to the distance of the image from the mirror (denoted as 'v'). This can be expressed as: - \( u = v \) 5. **Conclusion**: Based on the properties of a plane mirror, we can conclude that the image formed by a plane mirror is always of the same size as that of the object. **Final Answer**: An image formed by a **plane** mirror is always of the same size as that of the object. ---
