Webm is the magnification. hv is the height of the image. ho is the height of the object. Power of lens. We define the power of the lens as the reciprocal of the focal length of the lens used. P = 1 F. SI unit of power is Dioptre (D). The power of the concave lens is negative. The power of the convex lens can be positive. Optical magnification is the ratio between the apparent size of an object (or its size in an image) and its true size, and thus it is a dimensionless number. Optical magnification is sometimes referred to as "power" (for example "10× power"), although this can lead to confusion with optical power. For real images, such as images projected on a screen, size means a linear di…
