  • question_answer
    The near point and far point of a person are 40 cm and 250 cm respectively. Determine the power of the lens he/she should use while reading a book kept at distance 25 cm from the eye.

    A) 2.5D                                      

    B) 5.0D

    C) 1.5D                                      

    D) 3.5D

    Correct Answer: C

    Solution :

    If the object is placed at a distance 25 cm from the corrected lens, it should produce the virtual image at 40 cm. Thus, u = - 25 cm and v = - 40 cm The lens formula is \[-\pi /6\]                 \[\pi \]  \[250\mu F\]                 \[20\Omega \]  \[9\times {{10}^{4}}\,\,Hz\]                 \[16\times {{10}^{7}}\,\,Hz\]      \[8\times {{10}^{5}}\,\,Hz\]
