一、光的反射作图作图要点:1.物、像关于平面镜对称。2.平面镜是物点和像点连线的垂直平分线。3.反射角等于入射角,法线是反射光线和入射光线夹角的角平分线,且法线与镜面垂直,平面镜成像时,所有反射光线的反向延长线一定经过镜后的像。题型一:确定平面镜和反射光线的位置 First, the reflection of light mapping points: 1. Things, like the mirror on the plane. 2. The plane mirror is the vertical bisector of the object point and the point line. 3. The reflection angle is equal to the incident angle, and the normal line is the angle bisector of the angle between the reflected ray and the incident ray, and the normal line is perpendicular to the mirror plane. When the plane mirror is imaged, all the reversed extension lines of the reflected ray must pass through the mirrored image. Question type one: determine the position of the plane mirror and reflected light
