Characteristics of the Image Formed by a Convex Lens
- As with a curved mirror, the position and size of an image can be found by drawing a ray diagram.
- Any two of the following three rays are sufficient to fix the position and size of the image.
- The characteristics, position and size of the image formed by a convex lens depends on the object distance (u) relative to the focal length (f)
Position of Object: u > 2f
Distance of image: v < 2f
Position of Object: u = 2f
Distance of image: v = 2f
Position of Object: f < u < 2f
Position of Object: u = f
Position of Object: u < 2
