Question

lf an object is placed beyond the centre of curvature on the Principal axis of a convex lens, then the height of an image formed, when compared to the height of the object is a) small b) bigger C) equal D) point size image is formed​

Answer 1

Explanation:

When an object is placed beyond the centre of curvature then a ray of light AO which is parallel to the principal axis, pass through the focus F along the direction OF after refraction. While the other ray AC pass through the optical centre C and goes straight without any deviation according to the rule (2). These two refracted light rays intersect each other at point A’, between the focus F and centre of curvature 2F on the other side of the lens. In this way, a diminished, real and inverted image A’B’ is formed.

Answer 2

Answer:

That's height of image is bigger..... because the object is placed the center of curvature.
