Because the power of a lens is proportional to unity (one) divided by the focal length (see lens), the power of a lens in diopters is numerically equal to 1 m divided by the focal length in metres. The algebraic sign of the magnifying power indicates whether the lens causes an incident … novatti banking licence

WebThe power P of a lens is defined to be the inverse of its focal length. In equation form, this is. P=\frac {1} {f}\\ P = f 1. , where f is the focal length of the lens, which must be given in meters (and not cm or mm). The power of a lens P has the unit diopters (D), provided that the focal length is given in meters. WebWhen a lens is used to form an image of some object, the distance from the object to the lens u, the distance from the lens to the image v, and the focal length f are related by The focal length of a thin convex lens can be easily measured by using it to form an image of a distant light source on a screen.
