Unformatted text preview: Negative Thin Lens - Negative Object Distance A negative (diverging) thin lens is in air. It has a focal length of f as depicted in the attached figures. Light is propagating from left to right. An optical system (not shown) forms an image point that becomes the object point for this negative thin lens. In the first case, this virtual object point is located at a distance of f/ 2 to the right of the lens as shown in the upper figure. In the second case, this virtual object point is lo- cated at a distance of 3 f/ 2 to the right of the lens as shown in the middle figure. In the third case, this virtual object point is located at a distance of 2 f to the right of the lens as shown in the lower figure. For the three cases, calculate, showing all work, the location of the final image along the axis of the optical system to the left or to the right of the negative lens. The image due to the optical system (not shown) acts as the object for the negative lens....
