HOBIT, which stands for "Hybrid Optical Bench for Innovative Teaching and learning" is an educational platform that leverages the combination of numerical simulation and physical manipulation to facilitate learning of complex phenomena and motivate users about wave optics in practical work. HOBIT operates in real time and is…

Describes a spreadsheet that can be used to show the changes in intensity of Fraunhofer diffraction patterns produced by a single and double slits arrangement. Discusses a practical demonstration of diffraction that allows data to be logged and entered into the spreadsheet. (DDR)

Provides simple techniques for demonstrating and recording the effect of the changing shapes of moving objects when viewed through a moving slot. Includes a puzzle. A computer shareware program (IBM compatible) that simulates the distortions is available from the author. (MVL)

This high school physics resource is a simulator for optics, electronics, force, motion, and sound. Students can study oscillations, look at sound waves, and use probes to graph a wide variety of quantities. Over 100 activities are pre-written, and students can easily create their own additional activities using the multimedia editor. (WRM)
