Description

This Exploriments app has five activities that use highly interactive ray diagrams to introduce you to the basic concepts of optics. The app lets you explore reflective and refractive devices that are both converging and diverging in nature - the convex lens, concave mirror, convex mirror, concave lens and plane mirror. For each optical device, you can modify the focal length, object distance and object height and observe the effect it has on image formation, through a ray diagram format. A ray diagram is a schematic that traces light rays from the object to the optical device – where they are either reflected or refracted - then on to the position where the image is created. This is a good method for understanding the size, position and orientation of an image. The app renders ray diagrams in real-time with every change in the object distance, focal length or object height. The app describes the conventions that are needed to assign the proper signs to real, virtual, upright, inverted, diminished and magnified images. The app also helps you to apply the Gaussian Thin Lens Equation for solving numerical problems for given focal length and the different object and image properties. The accompanying theory content explains the characteristics of image formation in different optical devices with examples of real-world applications. The Exploriments Series of interactive simulation-based tools makes conceptual learning in science an engaging and insightful experience. Visit www.exploriments.com to know more.
