Object Distance in Concave Lens

Go Object Distance of Concave Lens = (Image Distance*Focal Length of Concave Lens)/(Image Distance-Focal Length of Concave Lens)

Object Distance in Convex Lens

Go Object Distance of Convex Lens = (Image Distance*Focal Length of Convex Lens)/(Image Distance-(Focal Length of Convex Lens))

Magnification of Concave Lens

Go Magnification of Concave Lens = Image Distance/Object Distance

Magnification of Convex Lens

Go Magnification of Convex Lens = -Image Distance/Object Distance

Power of Lens

Go Power of Lens = 1/Focal Length of Lens

Power of Lens Formula

What is Power?

In optics, power refers to the ability of a lens to converge or diverge light, defined as the inverse of its focal length. It is measured in diopters (D). A positive power indicates a converging lens (convex), while a negative power indicates a diverging lens (concave). Power is essential for understanding lens behavior in optical systems.

How to Calculate Power of Lens?
