It examines how these mirrors focus light, the occurrence of spherical aberration, and how image characteristics depend on the object's distance. The text includes equations for calculating image distance and size, and explores the formation of virtual images when objects are within the focal point.
If too large a piece of the mirror is used, the rays reflected from the top and bottom edges of the mirror will not pass through the focal point and the image will be blurry.

If you consider the smaller arrow to be the object and follow the rays backward, the ray diagram makes it clear that if an object is located between the center point and focal point, the image is inverted, larger, and at a greater distance.
