摘要
当光辐射到物体上,由于动量的传递,光对被辐射物体施加力.采用光纤将激光束投射到水中的聚苯乙烯球上,已知光源功率及功率分布、微粒的平衡位置,可直接计算出微粒在当前物理环境下受到的光辐射压力.
When exposed to electromagnetic radiation, light pressure will be exerted upon the surface of an object because of momentum transfer. In this experiment, laser beams are projected on a polystyrene ball in water through optical fiber, the radiation pressure can be calculated directly when the power, power distribution, and equilibrium position of particles are given.
