Comprehensive Experiments on Rotating Liquid for Mechanics Physics Lab

This Comprehensive Experiments on Rotating Liquid for Mechanics Physics Lab is designed for investigating the mechanical and optical properties of rotating fluids. When a liquid rotates, its free surface naturally forms a parabolic shape, providing an effective platform for studying gravitational acceleration, rotational dynamics, and optical focusing phenomena. The apparatus integrates semiconductor laser measurement technology with precision rotational speed monitoring, enabling accurate analysis of both the geometric and optical characteristics of the rotating liquid surface. The parabolic liquid surface also functions as a concave reflector, allowing the study of imaging and focal length relationships within a single experimental system.
