A doctor has prescribed a corrective lens of power + 1.5. D. Find the focal length of the lens. Is this prescribed lens diverging or converging.

Text Solution

Verified by Experts

Power of lens, p = 1/f
P = 1.5 D
`F=1//1.5 = 10//15 = 0.66 m`
A complex lens has a positive focal length Hence, it is a convex lens or a converging lens.
