The plane faces of two identical plano-convex lenses each having a focal length of 50 cm are placed against each-other to form a usual convex lens. The distance from this lens combination at which an object must be placed to obtain a real, inverted image which has the same size as the object, is -
Text Solution
Verified by ExpertsThe correct answer is:
A
= 
+ 
∴ f = + 25 cm
To form real, inverted image of same size object must be at 2f = 50 cm
