In traditional middle school optical experiments, the fixed light source with an iron stand is inconvenient to operate, and the water mist generated by a spray bottle has a short duration and easily affects the reflection effect, leading to many limitations in the experimental exploration of the law of light reflection. This paper constructs a motor-driven experimental platform for exploring the law of light reflection. It innovatively adopts motor drive to realize flexible adjustment of the light source angle, and uses a medical humidifier atomizer instead of a traditional spray bottle to ensure continuous and stable mist that is not easy to adhere to the mirror surface. Through modular design, the platform integrates the functions of light source adjustment, mist generation and reflection observation. It has a simple structure and convenient operation, effectively solving the pain points of traditional experimental devices, providing a more efficient practical tool for optical experiment teaching, and featuring low cost and easy promotion.
