The convex lens produces a real image of the same size as that of an object when the object is placed
At twice the focal length (2f)
At infinity
At principal focus of lens (f)
At principal focus of lens between optical centre (O) of the lens and its principal focus (F)
If the real inverted and highly diminished image of an object is formed at focus of the lens,then:
The object is at focus and the lens is concave
The object is at infinity and the lens is concave
The object is at focus and the lens is convex
The object is at infinity and the lens is convex
The maximum image distance in case of concave lens of focal length 'f' is
2f
F
3f
4f
