    【内容简介】     光现象
　　1．光的传播
　　能够发亮叫光源，月亮不是太阳是。
　　光的传播有条件，均匀介质才直线。
　　不同物中速度变，真空每秒三十万（千米）
　　C=3×105km/s=3×108km/s。
　　光的速度比声快，真空传光声不传。
　　2．光的反射
　　法线通过入射点，虚线垂直反射面。
　　反射入射居两边，反角入角总相等。
　　入法夹角为入角，入角增大反角增。
　　所有物体都反射，镜面反射漫反面。
　　3．平面镜成像
　　平面镜，成虚像，大小相等对称强。
　　物像到镜距相等，它们连线垂镜面。
　　作图反射反延长，虚线交点即像点。
　　所有像点组成像，虚像要用虚表示。
　　4．光的折射
　　光从一物进另物，同时发生反、折射。
　　斜线入水要折射，折线靠近于法线。
