Question

Identify the incorrect statement from the list of statements given below:

• A. A convex lens may produce a real and diminished image.
• B. A convex lens may produce a virtual and enlarged image.
• C. A concave lens always produces a virtual image of a real object.
• D. A concave lens can never produce a real image.

Answer 1

The correct option is D A concave lens can never produce a real image.

A convex lens produces a real, inverted and diminished image for object placed beyond $2F$.
However for position of object between optical centre $\left(O\right)$ and focus $\left(F\right)$, it produces virtual, erect and enlarged image.


$\Rightarrow$ A concave lens forms a virtual, erect image for all real objects.
However, for a virtual object is positioned between $O$ and $F$, then a real image is formed.

Why this question? Tip: Always remember that concave lens forms virtual image for all positions of a real object.
