WebEarlier in Lesson 5, we learned how light is refracted by double concave lens in a manner that a virtual image is formed. We also learned about three simple rules of refraction for double concave lenses: . Any incident ray traveling parallel to the principal axis of a diverging lens will refract through the lens and travel in line with the focal point (i.e., in … WebRay Diagrams for Lenses. The image formed by a single lens can be located and sized with three principal rays. Examples are given for converging and diverging lenses and for the cases where the object is inside and outside the principal focal length.
