一.光的折射规律的学习与运用光的折射规律,内容很多,死记硬背是无法运用的.其实它可简单归纳为:“共面、异侧;(除直射外)在空气中的光线与法线夹角大.”运用光的折射规律主要在作图、识图和现象解释类习题中.一般都作斜射时的光路,作图时,先找出入射点,画出法线,同时抓住:光线从空气射到水或玻璃中则靠近法线,反之光从水或玻璃射到空气中便远离法线.从几何上讲:光线在空气中与法线的夹角比光线在其他物质中与法线夹角大.简记为:空气中的“角”大.另外要注意“异侧”即折射光
1. The study and application of light’s refraction law The light’s refraction law has many contents and it can’t be used to memorize. In fact, it can be simply summed up as: “coplanar, opposite; (except direct) in the air And the angle between the normals is large.” The law of refraction using light is mainly used in graphing, graphing, and phenomenological interpretation. In general, it is used as an oblique light path. When drawing, first find the incident point and draw the normal line. At the same time, it is grasped that when light is blown into the water or glass from the air, it is close to the normal, whereas the light from the water or the glass hits the air and is far away from the normal. From a geometric point of view: the angle between the light and the normal in the air is smaller than the light. In other materials, the angle between the normal and the normal is large. It is simply described as: The “angle” in the air is large. Also note that the “opposite side” is the refraction light.
