प्रश्न
Name the mirror which forms an erect, virtual and enlarged image of an object. What is the position of object relative to the mirror?
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.
