Ray Diagram For Converging Lens

In this lesson we will see a similar method for constructing ray diagrams for double concave lenses. Furthermore the image will be inverted reduced in size smaller than the object and real.

Physics ल स Part 3 Ray Diagram Of Image Formation In Convex

Ray diagrams 2 of 4 convex lens step by step science.

Ray diagram for converging lens. There is one ray of light passing through the center of the lens. In this lab you will construct the six special ray diagrams for converging lenses. Shows how to draw ray diagrams to locate the image formed by a convex lens.

In each diagram an upward arrow has been provided as the object. 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. 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.

Ray diagrams for double convex lenses were drawn in a previous part of lesson 5. A ray diagram is a tool used to determine the location size orientation and type of image formed by a lens. Ray diagrams for lenses.

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. Converging and diverging lenses ray diagrams. Label it with an o.

The other ray of light always passes through the focal point of the lens. Image formation in convex lens can be explained with the help of three principal rays shown in figure. Examples are given for converging and diverging lenses and for the cases where the object is inside and outside the principal focal length.

Image formation by convex lens ray diagrams. Thin lens equation converging and dverging lens ray. Trick to drawing ray diagrams for converging lens.

For your convenience blank diagrams will objects already provided are located on this page in ie use landscape mode with margins of 05. Any ray of light that is parallel to the principal axis of the lens will pass through its focal point after refraction. The image formed by a single lens can be located and sized with three principal rays.

This position is located behind the lens and is usually labeled as f in ray diagrams. A diverging lens ray diagram follows three basic rules. In mirrors images are formed through reflection but lenses form images through refractionthis is explained with the help of ray diagrams as follows.

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. 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. A similar point the same distance in front of the lens is called the lens secondary focus f.

2 rays are enough to determine the position of imageobject.
