Concave Mirror Image Formation
A concave mirror can form a virtual, erect, and enlarged image when the object is placed correctly relative to its optical center.
Image Characteristics
- Virtual: The image is formed behind the mirror and cannot be projected onto a screen.
- Erect: The image orientation is the same as the object (upright).
- Enlarged: The image size is greater than the object size.
Determining Object Position
For a concave mirror, these specific image characteristics (virtual, erect, enlarged) occur only when the object is situated between the mirror's pole (P) and its principal focus (F).
When the object is placed in this region (P to F), the reflected rays diverge, and their virtual extensions meet behind the mirror, forming the described image.
Conclusion
Therefore, the correct position for the object to obtain a virtual, erect, and enlarged image from a concave mirror is between the pole and the focus.
Correct Option: The object is placed between the pole and the focus of the mirror.

With reference to street-lighting, how do sodium lamps differ from LED lamps?
1. Sodium lamps produce light in 360 degrees but it is not so in the case of LED lamps.
2. As street lights, sodium lamps have a longer life span than LED lamps.
3. The spectrum of visible light from sodium lamps is almost monochromatic while LED lamps offer significant colour advantages in street lighting.
