Ray diagram for an object placed inside the focal point of a converging lens.
Ray diagram for an object placed inside the focal point of a converging lens.
An object is placed a distance \(d_o = \dfrac{1}{2}f\) from a thin converging lens of focal length \(f\), as shown in the ray diagram below. A student looks through the lens from the side opposite the object. Which of the following correctly identifies the type of image formed and provides a valid physical justification?

OptionImage TypeJustification
ARealThe light rays are redirected by the converging lens and will eventually intersect at a distance \(f\) on the right side of the lens.
BVirtualThe light rays appear to originate from the left side of the lens, and the image can be captured on a screen placed at the left focal point.
CVirtualThe object is placed inside the focal length, which causes the lens to produce a virtual image at a distance \(0.5f\) from the lens on the same side as the object.
DVirtualThe refracted rays diverge from one another, and the image is located at a distance \(f\) from the lens on the same side as the object.
