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

Answer:

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(centre of curvature) of the lens.

Concave mirror

The concave mirror can give an erect and enlarged image.

  • When the concave mirror is placed very close to the object, a magnified and virtual image is obtained.
  • Concave mirrors provide real and virtual, erect and inverted, diminished, same-sized and magnified image depending upon the position of the object on the principal axis.
