Ray Diagrams for Convex Lens
Ray diagrams for convex lenses are based on the principle that convex lenses converge light rays passing through them.
The following points are to be kept in mind while drawing ray diagrams for convex lens:-
A ray of light passing through the optical center of a convex lens passes through the lens undeviated.
A ray of light parallel to the principal axis, on passing through the lens, gets deviated and passes through the focal point of the lens on the other side.
A ray of light passing through the focus of a convex, on passing through the lens, gets deviated such that it travels parallel to the principal axis on the other side.
Ray diagrams for convex lenses for different positions of the object:
When an object is placed at different positions with respect to the focal length, the double focal length, etc of the a convex lens, images formed of that object exhibit different characteristics according to its relative position to the lens. The location and characteristics of images formed in different scenarios can be predetermined by the help of which appropriate convex lenses are used in the correct positions in devices (or other applications such as correction of hypermetropia).
Having problem with Hypermetropia Definition keep reading my upcoming posts, i will try to help you.
Characteristics of an image
The following six different positions of objects produce images of different characteristics in convex lenses. The ray diagrams for convex lens are given below:-

Characteristics of an image
- Position:- Where the image is formed with respect to the object.
- Size:- Is the image smaller than, equal to, or larger than its object?
- Nature:- Whether the image is inverted or upright, and whether it is real or virtual.
