The law of refraction, discovered first empirically by Willebrord SNELL, then subsequently derived formally by Descartes and Fermat, states that sin r = K sin i, where i is called the angle of incidence, the angle between the incident ray and the normal to the refracting surface.
折射的轨律，首先被 Willebrord SNELL 靠经验发现，接着后来正式被笛卡尔和 Fermat 认定，规定 sin r = K sin i ，这里 i 被称作入射角，入射光线和法线到折射平面之间的夹角。
