摘要

Infrared emitting diodes (IREDs) have found many applications in remote control systems, security units and telecommunication networks in the past ten years. They are cheap and durable and the IR they emit can easily be detected with cheap web-cams and other digital cameras. Using accessories readily available in school laboratories, we have developed some interesting experiments that are suitable for use by teachers in demonstration halls, and by students as group experiments and project investigations.
