Question

a person needs a lens of power + 2.5 diopter for correcting his vision name the defect of the vision he is suffering from which type of lens will be using for correcting the defect also find the focal length of the lens​

Answer 1

Answer:

Hypermetropia (convex lens required)

Explanation:

If the power of the lens is positive,then the focal length is also positive. Hence it is a convex lens as convex lens has positive focal length.

Also, we require convex lens, while suffering from hypermetropia.
