绘制光路图
Drawing Ray Diagrams
绘制光路图，展示光线在平面镜上的反射（入射角等于反射角）以及光线在两种介质交界处的折射；利用光路图确定像的位置，并解释透镜和镜子是如何工作的。
Draw ray diagrams to show reflection at a plane mirror (angle of incidence = angle of reflection) and refraction at a boundary between media; use ray diagrams to locate images and explain how lenses and mirrors work
学习证据 / Evidence
- 画出平面镜的光路图，标出入射光线、法线、反射光线和虚像。
- 画出光路图，展示光线从空气进入玻璃时向法线方向偏折。
- 利用光路图确定凸透镜所成像的位置，并说明该像是实像还是虚像。
- Draw a ray diagram for a plane mirror showing the incident ray, normal, reflected ray, and virtual image
- Draw a ray diagram showing a ray bending towards the normal when passing from air into glass
- Use a ray diagram to locate the image formed by a convex lens and describe whether it is real or virtual
评估问题 / Assessment
{{name}}能否画出一幅示意图，展示光线从镜子表面反射或从空气进入玻璃时发生偏折，并正确标出角度？
Can {{name}} draw a diagram showing how a ray of light bounces off a mirror or bends when it passes from air into glass — labelling the angles correctly?
