Converging Lenses

What better way to learn how to use a microscope than building your own? A lab investigation has scholars use lenses from magnifying glasses and sheets of cork to design their own compound microscopes. They calculate focal length...

All aspects of the path of light are included in a great summary. Internal reflection and the angles of paths in different materials are explained and the behavior of visible light through lenses and the effect on focal points are...

This is an informative site from Georgia State University. It gives a discussion of the thin lens equation and an illustration of its use in determining the image distance based upon the object distance and the focal length.

Have you ever wondered why some people need glasses and others don't? It's because of the way light is focused by the lens in your eye. This lens, like magnifying glasses, eyeglasses, and contact lenses, is considered a thin lens.

This video offers examples of using the thin lens equation.[12:56]

This lesson explains what lenses are, the different between a converging and diverging lens, the difference between a double convex and double concave lens, and gives definitions for terms related to lenses.

This lab is designed to have students investigate the changes that occur to images formed by converging lenses based on the focal length of the lens, the height of the object and the location of the object. This video will help...

How do contact lenses work? The simulation allows young scientists to explore focal length and lens type to see how and why contact lenses work. Pupils control the focal length for an eye and a lens, the type of lens, and the distance...

Add a ray of light to the class as young scientists learn important foundational concepts. Assist pupils with focal lengths as they study ray diagrams. Pupils review images and compare them to mirrored images before solving problems on...
