Question

When the object is placed between the optical centre and the principal focus of a convex lens, then the image formed is real, inverted and enlarged image real, inverted and diminished virtual, erect and diminished image virtual, erect and enlarged image​

Answer 1

Answer:

i) When object is placed at 2F1 (centre of curvature) distance from the optical centre on the principal axis of a convex lens a real and inverted image of the same size of object is formed. An erect magnified and virtual image is formed, when an object is placed between the optical centre and principal focus of a lens.

Explanation:

Answer 2

When the object is placed between the optical centre and the principal focus of a convex lens, then the image formed is virtual, erect and enlarged image​

• A ray starting from the object travels parallel to the principal axis and passes through the second focus.
• Another ray from the object passes through optical centre of the lens undeviated.
• The two refracted rays, when extended in the backward direction appear to meet behind the lens.
• This image is formed on the same side of the lens as that of the object.
• It is virtual, erect and larger than the object.
