Principle Ray II. Preliminary on the object side of the lens ray II heads toward the plane of the lens along a line that is parallel to the principle axis of the lens. At the plane of the lens it suddenly adopts a path that takes it directly away from the focal point that is on the same side of the lens as the object. If you outline that ray straight back the trace-back line passes through said focal point.
Draw a ray diagram to show the formation of image of an object placed among the optical centre and focus of the convex lens. Write the characteristics of image formed. Using this d
