A lens is formed by placing the plane faces of two identical plano-convex lenses (each of focal length 40 cm) touching each other. It is used to obtain a real, inverted image of the same size as the object. The distance of the object from the lens is: |
20 cm 40 cm 80 cm 160 cm |
40 cm |
The correct answer is Option (2) → 40 cm |
