    The power of the eye for a person seeing an object which is distanced a distance 7.25 cm is 63.75 diptore

    Explanation:

    To find the power of the eye

    we have the formula,

    P=1/f= 1/d0 +1/di

    Where,

    do denotes the distance between eyes length and the object

    di  denotes the distance between eyes length and the image

    Given data

    do=7.25 cm di=2.00 cm

    substitute in the formula

    P=1/f= 1/d0 +1/di

    P= 1/0.0725 +1/0.02=13.79

    P=63.79 D

    The power of the eye for a person seeing an object which is distanced a distance 7.25 cm is 63.75 diptore
