Ray Diagram For Converging Lens

In this lesson we will see a similar method for constructing ray diagrams for double concave lenses. Image formation in convex lens can be explained with the help of three principal rays shown in figure.

A diverging lens ray diagram follows three basic rules.

Ray diagram for converging lens. 11 draw a ray diagram for a diverging lens that has a focal length of 108 cm when an object is placed 324 cm from the lenss surface. The other ray of light always passes through the focal point of the lens. 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.

In each diagram an upward arrow has been provided as the object. Any ray of light that is parallel to the principal axis of the lens will pass through its focal point after refraction. Examples are given for converging and diverging lenses and for the cases where the object is inside and outside the principal focal length.

Any incident ray of light that passes through the focus of the lens before getting refracted will emerge parallel to the principal axis on refraction. There is one ray of light passing through the center of the lens. The image formed by a single lens can be located and sized with three principal rays.

Ray diagrams for double convex lenses were drawn in a previous part of lesson 5. Converging and diverging lenses ray diagrams. A similar point the same distance in front of the lens is called the lens secondary focus f.

Image formation by convex lens ray diagrams. Shows how to draw ray diagrams to locate the image formed by a convex lens. This position is located behind the lens and is usually labeled as f in ray diagrams.

In this lab you will construct the six special ray diagrams for converging lenses. A ray diagram is a tool used to determine the location size orientation and type of image formed by a lens. The distance from the center of the lens to the principal focus is called the focal length of the lens and is represented by the variable f.

Thin lens equation converging and dverging lens ray. 12 draw a ray diagram for an object placed 60 cm from the surface of a converging lens with a focal length of 120 cm. In mirrors images are formed through reflection but lenses form images through refractionthis is explained with the help of ray diagrams as follows.

Trick to drawing ray diagrams for converging lens. Ray diagrams for lenses. Label it with an o.

2 rays are enough to determine the position of imageobject. Furthermore the image will be inverted reduced in size smaller than the object and real. For your convenience blank diagrams will objects already provided are located on this page in ie use landscape mode with margins of 05.
