Question

People who do very detailed work close up, such as jewelers, often can see objects clearly at a much closer distance than the normal 25.0 cm . What is the power of the eyes of a woman who can see an object clearly at a distance of only 7.25 cm ? Assume a distance from the eye lens to the retina of 2.00 cm .

Answer 1

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

Step-by-step 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
