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
