    A converging lens has a focal length of 50 cm The power of the lens is:

    A)  \[+5D\]               

    B)         \[+2D\]

    C)  \[+0.5D\]           

    D)         \[-0.5D\]

    E)  \[-2D\]

    Correct Answer: B

    Solution :

    Power of a lens is inverse of focal length (in metres) \[P=\frac{1}{f}\] Given,     \[f=50\text{ }cm\] \[\therefore \]  \[P=\frac{100}{50}=+2D\]
