WebAn object is placed to the left of two converging lenses, as shown in (Figure 1). Lens 1 has a focal length f and lens 2 has a focal length 2f. The lenses are separated by a distance of 6f. An object of height h is then placed a distance of 2f to the left of lens 1. Calculate the following quantities in terms of f and h (specify the Figure "↑ ... WebThe focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a system converges light, while a negative focal length indicates that the system diverges light.
