射出透明体的光线和射入透明体的光线之间的夹角统称为偏向角.求偏向角是几何光学的重要内容,这里要用到光的传播规律和平面几何知识,由于光路图较复杂,作图和标记时要保持清晰.以免误解.
The angle between the light emitted from the transparent body and the light incident on the transparent body is collectively referred to as the deflection angle. The deviation angle is an important content of geometric optics. Here, the light propagation law and plane geometry knowledge are used, and the light path diagram is complicated. Keep clear of drawings and markings to avoid misunderstandings.
