Examples are given for converging and diverging lenses and for the cases where the The third ray is not really needed, since the first two locate the image. In this section of Lesson 5, we will investigate the method for drawing ray diagrams for objects placed at various locations in front of a double convex lens.

2) A ray that (seems to) pass(es) through F’, will end up parallel to the principal axis. 3) A ray that passes through the center of the lens, will continue virtually.(10) Draw a ray diagram for a cm tall object placed cm from a converging lens having a focal length of cm. (11) Draw a ray diagram for a diverging lens that has a focal length of cm when an object is placed cm from the lens’s surface.

Convex lens can be defined as the lens which the center part is bulged outwards and the thickness is reduced along the edges. When a light ray is incident on the surface of a convex lens, it gets refracted and emerges out at different directions.
Convex lens can converge the parallel rays to a point (focal point) since it is known as converging. Ray Diagrams for Lenses.
The image formed by a single lens can be located and sized with three principal rays. Examples are given for converging and diverging lenses and for the cases where the object is inside and outside the principal focal length.
The ray diagram above illustrates that when the object is located at a position beyond the 2F point, the image will be located at a position between the 2F point and the focal point on the opposite side of the lens. Furthermore, the image will be inverted, reduced in size (smaller than the object), and real.Converging Lenses – Ray DiagramsDiverging Lenses – Ray Diagrams
