The image size for a thick lens can be calculated using the equation: m = -di/do = hi/ho = f/(f-do), where m is the magnification, di is the image distance, do is the object distance, hi is the image height, ho is the object height, and f is the focal length of the lens.
The image size refers to the actual physical size of the image formed by a thick lens, while the magnification is a ratio of the size of the image to the size of the object. The magnification can be either positive or negative, depending on whether the image is upright or inverted.
The curvature of a thick lens affects the image size by altering the focal length and therefore the magnification of the lens. A lens with a larger curvature will have a shorter focal length and a larger magnification, resulting in a larger image size.
Yes, the image size of a thick lens can be larger than the object size. This occurs when the object is placed within the focal length of the lens, resulting in a magnification greater than 1. In this case, the image will be larger than the object.
The sign of the image size in the thick lens equation is determined by the relative positions of the object and the lens. If the image is on the same side as the object, the image size will have a positive sign. If the image is on the opposite side of the lens, the image size will have a negative sign.
