Optics: Image Formation by a Converging Lens

Very Hard Physics Optics

In a laboratory setting, a biologist is studying the behavior of light as it passes through a lens that has a focal length of 20 cm. The biologist directs a beam of light originating from a point source located 30 cm away from the lens along the optical axis. The lens used is a converging lens.

The biologist measures the position of the image created by this lens. Given the properties of the lens and the distances involved, determine the nature of the image produced by the lens.

The image is real, inverted, and located 60 cm on the other side of the lens.

The image is virtual, upright, and located 12 cm on the same side as the object.

The image is real, upright, and located 15 cm on the other side of the lens.

The image is virtual, inverted, and located 30 cm on the same side as the object.
