Two converging achromatic lenses with focal lengths of about 6 cm and 13 cm Graphical Analysis software Vertical rod in table-top stand Printed arrow Font size 11 Smart phone with camera or webcam Support ring for Phone Physical Principles: Focal Length For the rays shown in Figureslight is assumed to be coming from the left, and going toward the right.

A converging lens always has two focal points, the primary focal point on the near side of the lens towards the oncoming light rays and a secondary focal point on the far side of the lens away from the oncoming light rays.

Light diverging from the primary focal point and approaching a converging lens will exit the lens with the rays parallel. Parallel light rays approaching a converging lens will converge at the secondary focal point.

See Figures 1 and 2. Light coming from very distant objects can be approximated with parallel rays. The distance from the lens to the focal points is called the focal length. For a converging lens, the focal length is always positive, for a diverging lens it is always negative.

Ray Diagrams A Ray Diagram is a graphical method of predicting the characteristics of an image produced by a lens. First draw a set of axis and draw the lens at the origin. Then locate the position of the two focal points and the object.

This should be done to scale so that the position and size of the resulting image are accurate. Next draw the three reference rays: Reference rays originate from the object, travel through the lens and are refracted.

Where any two rays intersect, the image is formed. The third ray should pass through the same intersection point; this just confirms the location of the image. Remember, light is refracted differently when encountering converging and diverging lens, the rays will be refracted in different ways.

Ray Diagram for a converging lens. The Parallel Ray 1 is drawn parallel to the axis then refracted towards the back focal point. The Central Ray 2 proceeds straight through he center of the lens.

The Focal Ray 3 is drawn towards the focal point then refracted parallel to the axis.The Ellington Lab conducts research in synthetic biology, protein engineering, and DNA nanotechnology at the University of Texas at Austin.
