    Consider the following statements.
    1. The images produced by concave mirrors are always real images.
    2. The images produced by flat mirrors are always virtual images.
    3. Converging lens can produce virtual as well as real images.
    Which of the statements given above are correct?

    A)  1 and 2           

    B)  2 and 3  

    C)  1 and 3

    D)  All of these

    Correct Answer: B

    Solution :

    [b] Real images can be produced by concave mirrors and converging lenses. But, a converging lens and concave mirror are also capable of producing virtual images if the object is within the focal length. Thus, Statement 1 is incorrect, while Statement 3 is correct. Flat mirrors can never produce real image because rays never really converge, so Statement 2 is also correct.
