CloudLabs Converging Lens
Read full descriptionHide full description
This simulator recreates an optical table with a converging lens and two test objects. The goals of this lab are to experimentally find the focal length, radius of curvature, and power of the lens, as well as find the magnification of the image and determine whether or not it is inverted. During the laboratory development you will be able to observe the changes in the size of the formed image, as the distance between the object and the lens is varied.
