Web3.1 Images formed by Mirrors and Lenses • Images • Image formation by mirrors • Images formed by lenses Object-Image • A physical object is usually observed by reflected light that diverges from the object. • An optical system (mirrors or lenses) can produce an image of the object by redirecting the light. – Real Image – Virtual Image WebTable 3 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). dogfish tackle \u0026 marine
