摘要: 首先对偏向角的公式进行了推导,重点讨论了在有出射光线的情况下,三棱镜的规格参数、棱镜顶角和折射率对入射角和折射角的影响; 然后,建立了偏向角与入射角、棱镜顶角及折射率之间的关系,并阐述了关系曲线的物理意义; 最后对最小偏向角进行了研究.

Abstract: The formula of the deviation angle is deduced. The influence of the prism angle and the refractive index on the relationship between the angle of incidence and the angle of refraction are discussed. The angle of inclination and the angle of incidence are discussed. The relationship between the vertex angle and the refractive index,and the physical meaning of the curve are expounded. Finally,the minimum deflection angle is studied.
