Answer:
Step-by-step explanation:
There is a convex lens M N is placed. An object AB is placed at a distance more than two focal lengths of the lens.
A ray of light is starting from point A and parallel to the principal axis, then after refraction it goes from the focus.
Another ray which goes through the optical centre of the lens becomes undeviated after refraction.
The two refracted rays meet at the point A', So A'B is the image of AB.
The nature of image is real, inverted and diminished.
