Convex lens imaging law

The imaging law of convex lens refers to that the object is placed outside the focus and forms an inverted real image on the other side of the convex lens. It can be divided into three situations: reduction, amplification and so on. Generally, if the object distance is greater than 2 times the focal length, it is reduced, the object distance is equal to 2 times the focal length, and the object distance is less than 2 times and greater than 2 times the focal length, it is enlarged. What is the imaging law of convex lens? When learning physics in junior middle school, you will learn the imaging law of convex lens. The imaging law of convex lens is an optical law. We generally call the image that can be presented on the light screen as real image, otherwise it is virtual image, and generally the real image is inverted, and the virtual image is upright.

The imaging law of convex lens is the real image formed by placing the object outside the focus and standing upside down on the other side of the convex lens. It can be divided into three cases: reduction, amplification and enlargement. When the object distance is greater than 2 times the focal length, the image distance is between 1 and 2 times the focal length, showing an inverted and reduced real image.

When the object distance is equal to twice the focal length, the convergence is also at twice the focal length, showing a real image such as handstand and so on. The object distance is less than 2 times the focal length, more than 1 time the focal length, and the distance is more than 2 times the focal length. At this time, the inverted and enlarged real image is presented.
