उत्तर
The concave mirror can form an erect, virtual, and enlarged image of an object when the object is placed between the mirror and its focal point (F).
Explanation:
- When the object is positioned closer to the mirror than its focal point, the reflected rays appear to diverge, and the image forms behind the mirror.
- The image is:
- Erect (upright),
- Virtual (cannot be projected on a screen),
- Enlarged (magnified).
Example:
This principle is often used in makeup mirrors and shaving mirrors to provide a magnified view of the face.
