A person is determining the description of the image formed by a converging lens by implies of a ray tracing diagram. The person has gotten so far as drawing one principal ray. What is incorrect with the way the person has drawn that one principal ray.
Ans:
The principal ray in question at this time is the one that travels along a line that passes by the focal point on the same side of the lens as the object. In the case at hand the thing is closer to the lens than the focal point so the ray leaves the object and travels directly away from the focal point in order to be on that line and to be travelling toward the plane of the lens.
At the plane of the lens this principle ray accepts a new straight line path. The latest path is parallel to the principal axis of the lens.
