Question

An erect and enlarged image of an object is formed on a screen. Explain how this could be possible.

Answer 1

1. The concave mirror can give an erect and enlarged image.
2. When the concave mirror is placed very close to the object, a magnified and virtual image is obtained.
3. Concave mirrors provide real and virtual, erect and inverted, diminished, same-sized and magnified images depending upon the position of the object on the principal axis.
4. An erect and enlarged image of an object is formed on a screen if the object is placed upside down between F(focus) and 2F(center of curvature) of the lens.
