A light pen works by detecting light emitted by a computer monitor or screen when the pen's tip touches the surface. The pen has a light-sensitive photodiode at the tip, which detects the light and sends a signal back to the computer to identify the pen's position on the screen. This allows users to interact with software by pointing and selecting on the screen.
