Ray Diagram For Converging Lens

Front focal point back focal point front focal lenght distance ffl back focal lenght distance bfl optical axis focus center physics and chemistry by a clear. 122 ray diagrams lenses in this video paul andersen explains how ray diagrams for lenses can be used to determine the size and location of a refracted image.

Converging Lenses Ray Diagrams

In mirrors images are formed through reflection but lenses form images through refractionthis is explained with the help of ray diagrams as follows.

Ray diagram for converging lens. Images may be either real or. The other ray of light always passes through the focal point of the lens. A ray diagram is a tool used to determine the location size orientation and type of image formed by a lens.

There is one ray of light passing through the center of the lens. Image formation by convex lens ray diagrams. Image formation in convex lens can be explained with the help of three principal rays shown in figure.

To see why this is so a ray diagram can be used. Converging and diverging lenses ray diagrams. You can see a listing of all my videos at my website httpwwwstepbystepscienc.

Trick to drawing ray diagrams for converging lens. 1 a converging lens refracts the light so that any ray of light parallel to the principal axis the thick horizontal line is turned to pass through the focal point. 2 rays are enough to determine the position of imageobject.

Ray diagrams for lenses. A virtual image is formed if the object is located less than one focal length from the converging lens. In this lesson we will see a similar method for constructing ray diagrams for double concave lenses.

Rays of light parallel to the principal axis are all refracted through the focal point. 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. Converging lens optics flash animation for optics learning interactive physics simulations interactive physics animations interactive flash animation to learn how to get an clear image of an object on a screen.

Ray diagrams for double convex lenses were drawn in a previous part of lesson 5. 12 draw a ray diagram for an object placed 60 cm from the surface of a converging lens with a focal length. A ray diagram for the case in which the object is located in front of the focal point is shown in the diagram at the right.

Observe that in this case the light rays diverge after refracting. To explain how to draw the diagrams there are two key things to remember. Examples are given for converging and diverging lenses and for the cases where the object is inside and outside the principal focal length.

10 draw a ray diagram for a 30 cm tall object placed 100 cm from a converging lens having a focal length of 150 cm. The image formed by a single lens can be located and sized with three principal rays. Shows how to draw ray diagrams to locate the image formed by a convex lens.
