Question

What should be the position of the object on the principal axis so that a real and inverted image of the same size as the object is obtained using a convex lens? Draw a ray diagram to show the formation of the image.

Answer 1

            Object at 2F₁ Forms the same-size image at 2F₂

The object must be placed at 2F₁ (twice the focal length) in front of the convex lens.
