Convex Lens Ray Diagram

In this lesson we will see a similar method for constructing ray diagrams for double concave lenses. 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.

A ray diagram is a tool used to determine the location size orientation and type of image formed by a lens.

Convex lens ray diagram. Ray diagrams for double convex lenses were drawn in a previous part of lesson 5. Shows how to draw the ray diagrams for locating the image produced by a concave lens and a convex mirror. Move the point named focus to the right side of the lens to change to a concave lens.

The ray passing through optical centre passes straight through the lens and remains undeviated. One goal of a ray diagram is to determine the location size orientation and type of image that is formed by the double convex lens. This point is known as the focus and the distance between the centre of the lens to the focus is called the focal length of convex lens.

However if one of the surfaces is flat and the other convex then it is called a plano convex lens. There is another type of lens known as concave lens. Ray diagrams for concave lenses.

The ray parallel to the principal axis passes through the focal point after refraction by the lens. Typically this requires determining where the image of the upper and lower extreme of the object is located and then tracing the entire image. 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.

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. Simulation of image formation in concave and convex lenses. Move the point named focus to change the focal length.

Difference between convex and concave lens. An erect virtual image smaller than the object. Move the tip of the object arrow to move the object.

You can see a listing of all my videos at my websit. After completing this lab you will be able to explain how lenses work explain the difference between convex and concave lenses draw ray diagrams to analyze the image produced by a lens and. 12 draw a ray diagram for an object placed 60 cm from the surface of a converging lens with a focal length.

The image is always formed inside the focal length of the lens. The ray diagrams for concave lenses inside and outside the focal point give similar results.
