Question

Susan is quite nearsighted; without her glasses, her far point is 34 cm and her near point is 17 cm . Her glasses allow her to view distant objects with her eye relaxed. With her glasses on, what is the closest object on which she can focus?

Answer 1

`u=34cm`

Step-by-step explanation:

From the question we are told that:

Far point is
`V=34 cm`

Near point is
`u=17 cm`

Therefore

Focal Length

`f=-34cm`

Generally the equation for the Lens is mathematically given by

`(1)/(u)=(1)/(f)-(1)/(v)`

`(1)/(u)=(1)/(-34)-(1)/(-17)`

`u=34cm`
