Find the Focal Length of the Lens. is the Prescribed Lens Diverging Or Converging? - Science
A doctor has prescribed a corrective lens of power +1.5 D. Find the focal length of the lens. Is the prescribed lens diverging or converging?
Power of lens, P= 1/f
f= 1/1.5 = 10/15 = 0.66 m
A convex lens has a positive focal length. Hence, it is a convex lens or a converging lens.
