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
