A person is tasked with creating a ray diagram to conclude the characteristics of the image of an object formed by a concave lens. The person has accurately drawn the principal axis of the lens, a lens icon to specify the kind of lens, the plane of the lens, the object and correctly drawn and labelled the focal points. After that the person draws the incoming ray shown. Which one of the subsequent statements about that ray is most correct?
Ans:
In the situation of a diverging lens one of the principal rays is a ray that leaves the object and travels directly toward the focal point on the other side of the lens. At the plane of the lens this ray suddenly changes its direction of travel to one which is parallel to the principal axis of the lens.
