The final image position in a system of two converging lenses is determined by the combined effect of the individual lenses. The first lens forms an intermediate image, which then serves as the object for the second lens. The final image position is where the light rays from the second lens converge.
The final image distance can be calculated using the lens equation, which is given by 1/f = 1/do + 1/di, where f is the focal length of the lens, do is the object distance, and di is the image distance. In a system of two lenses, the object distance is the distance from the first lens to the object, and the image distance is the distance from the second lens to the final image.
When the two converging lenses are moved closer together, the final image will move closer to the lenses. This is because the combined effect of the lenses is to increase the overall power of the system, resulting in a shorter focal length and a closer image distance.
Yes, the final image in a system of two converging lenses can be virtual. This can occur when the first lens forms a virtual image, which then becomes the object for the second lens. In this case, the final image will also be virtual and will appear on the same side of the second lens as the object.
The magnification of the final image in a system of two converging lenses is the product of the magnification of each individual lens. This can be calculated using the equation m = -di/do, where di is the image distance and do is the object distance for each lens. The overall magnification will depend on the relative positions and magnifications of the two lenses.
