Question

A person cannot see objects clearly beyond 100cm then power of the lens to correct the vision is

Answer 1

Answer:

hii!

here is ur answer!

Explanation:

the person is suffering from myopia

so the image of distant object should fall on far point i.e 100cm

the lens formula is

1/v- 1/u=1/f

here v is distance of image from pole

u is distance of object from pole

f is focal length of lens

here u is infinity

image should fall on 100cm

1/100 =1/f

p=100/f(here f should be in cm)

p=100/100=1 D( diopters)

D is unit of power

so p=1D
