Detailed explanation-1: -The equation for the magnification of a lens is simply the height of the image divided by the height of the object. Where M is the magnification, hi is the height of the image, and ho is the height of the object.
Detailed explanation-2: -The magnification equation states that M = Hi/Ho =-Di/Do, where M is the magnification, Hi is the height of the image, Ho is the height of the object, Di is the distance from the lens to the image and Do is the distance of the object to the lens. The minus sign signifies the fact that the image will be inverted.
Detailed explanation-3: -The magnification produced by a lens is defined as the ratio of the height of the image to the height of the object. The magnification produced by a lens is defined as the ratio of the image distance to the object distance.
