Question

$\left(i\right)$ Where should an object be placed so that a real and inverted image of the same size as the object is obtained using a convex lens?
$\left(ii\right)$ Draw a ray diagram to show the formation of the image specified in the part $\left(i\right)$.

Answer 1

$\left(i\right)$ When an object is placed at $2F_1$ (centre of curvature) of the convex lens, a real and inverted image with the same size of the object is formed at $2F_2$ (centre of curvature) on the other side of the lens.
$\left(ii\right)$ Ray diagram of a convex lens to show the formation of a real and inverted image of the same size as the object is shown.
