Question

A biconvex lens with an object at 2F. Rays are drawn both parallel to the principal axis and through the center of the lens. The ray parallel is bent through the focal point on the image side of the lens. The ray straight through the center of the lens is not bent. The rays converge at the image at 2F on the image side of the lens, and the image is inverted and the same size as the object. What are the characteristics of the image formed by the object?

a) The image is located on 2F in front of the lens, virtual, upright, and the same size as the actual object.
b) The image is located on 2F behind the lens, real, inverted, and the same size as the actual object.
c) The image is located at the focal point in front of the lens, virtual, upright, and larger than the actual object.
d) The image is located at the focal point behind the lens, real, inverted, and smaller than the actual object.

Answer 1

The characteristics of the image formed by a biconvex lens with the object at 2F is that the image will be located at 2F on the image side, real, inverted, and the same size as the object.

Step-by-step explanation:

The characteristics of the image formed when an object is placed at the 2F point of a biconvex lens are important for understanding basic optics. When the object is at 2F, the rays of light that pass through the lens and either go through the center or are parallel to the principal axis will converge at the 2F point on the other side of the lens. This results in the formation of a real, inverted image that is the same size as the actual object. Therefore, the correct answer to the characteristics of the image formed is that the image is located on 2F behind the lens, is real, inverted, and the same size as the actual object.
