The plane faces of two identical plano-convex lenses each having focal length of 40 cm are pressed against each other to form a usual convex lens. The distance from this lens, at which an object must be placed to obtain a real, inverted image with magnification one is
Text Solution
Verified by ExpertsThe correct answer is:
B
To obtain, an inverted and equal size image, object must be paced at a distance of 2 f from lens, i.e. 40 cm in this case.
