WebAug 4, 2008 · There are two main types of lenses, known as convex (or converging) and concave (or diverging). Convex lenses In a convex lens … WebLight rays diverge upon refraction; for this reason, the image location can only be found by extending the refracted rays backwards on the object's side the lens. The point of their intersection is the virtual image location. It would appear to any observer as though light from the object were diverging from this location.
