Converging Lens: Definition, Diagram, Equation

WebTable 1 summarizes the three types of images formed by single thin lenses. These are referred to as case 1, 2, and 3 images. Convex (converging) lenses can form either real or virtual images (cases 1 and 2, respectively), whereas concave (diverging) lenses can form only virtual images (always case 3). WebLensmaker's Equation. Equation to calculate the focal length of a lens in air: P = 1 f = ( n − 1) [ 1 R 1 − 1 R 2 + d ( n − 1) n R 1 R 2] : (Focal length is measured from the center of the lens): The power of the lens P (in diopters for f in meters) is equal to the inverse of the focal length, f .: The power is determined by the index of ...
