Question

The near point of a hypermetropic eye is 1meter what is the power of lens

Answer 1

Answer:

The power of lens is 1 dioptre.

Explanation:

The formula for power (P) = 1 / f

Remember that focal length should be in metre.

$(p) = \frac{1}{f}$

$(p) = \frac{1}{1}$

:. (P) = 1 dioptre

Also, Convex lens is used to be corrected as hypermetropic eye.

Hence, the focal length should be positive in convex lens.

Hope , you got the correct answer !!
