光路图与成像
Ray Diagrams & Images
画出光路图，展示平面镜和凸透镜的成像过程，并判断像是实像还是虚像、放大还是缩小、正立还是倒立。
Construct ray diagrams to show the formation of images by plane mirrors and converging lenses, identifying whether images are real or virtual, magnified or diminished, upright or inverted
学习证据 / Evidence
- 能准确画出平面镜的光路图，表明所成的像是虚像、正立且等大的。
- 能画出凸透镜的光路图，展示成像过程。
- 能利用光路图判断像是实像还是虚像，以及像形成在透镜的哪一侧。
- 能运用光路图知识解释眼镜、相机或投影仪的工作原理。
- Draws an accurate ray diagram for a plane mirror showing a virtual, upright, same-size image
- Draws a ray diagram for a converging lens to show image formation
- Uses a ray diagram to determine whether the image is real or virtual and which side of the lens it forms
- Applies ray diagram knowledge to explain how glasses, cameras, or projectors work
评估问题 / Assessment
如果要求{{name}}在图上画出照镜子时自己的影像出现在哪里，{{name}}能画出正确的光路，并说明这个像是实像还是虚像，以及它实际上看起来在哪个位置吗？
If {{name}} was asked to show on a diagram where their reflection appears to be when they look in a mirror, could they draw the correct ray paths and explain whether the image is real or virtual — and where it actually appears to be located?
