Name the defect of vision the person is suffering from.
Show Hint
For correcting hypermetropia, convex lenses are used, and their power is calculated as \( P = \frac{1}{f} \). A positive power indicates the use of convex lenses.

Show Solution
Solution and Explanation
A person with hypermetropia (farsightedness) has trouble seeing close objects, but can see distant ones clearly. This happens because the eye is too short or the cornea isn't curved enough, which makes light focus past the retina. Convex lenses fix this by bending light inward before it enters the eye.

- A compound microscope is designed with two symmetric biconvex lenses. The objective lens is cut vertically, creating two identical plano-convex lenses. One of them is used in place of original objective lens. To retain same magnification keeping the object distance unchanged, the tube length has to be:
