Virtual Image Formation by Optical Devices
The question asks which optical device can produce a virtual image that is larger than the object. Let's analyze the properties of each option:
Concave Mirror Properties
A concave mirror can form different types of images depending on the object's position:
- When an object is placed beyond the focal point (F), it forms a real image.
- When an object is placed between the pole (P) and the focal point (F), it forms a virtual, erect, and magnified image behind the mirror.
Therefore, a concave mirror meets the criteria.
Other Optical Devices
Let's examine why the other options do not fit:
- Plane mirror: Always forms a virtual image that is erect and the same size as the object. It cannot produce magnification.
- Concave lens: Always forms a virtual, erect, and diminished image (smaller than the object), regardless of the object's position.
- Convex mirror: Always forms a virtual, erect, and diminished image (smaller than the object), regardless of the object's position.
Final Answer Derivation
Based on the analysis, only the concave mirror is capable of producing a virtual image that is larger than the object when the object is positioned appropriately (between the pole and the focal point).
Correct Option: A. Concave mirror
