一、利用平面镜改变光的传播方向 例1 如图1所示,光线AO以20°的入射角射到平面镜上。若将平面镜顺时针转动5°后,则反射光线与入射光线之间的夹角为____。
First, the use of flat mirrors to change the direction of light propagation Example 1 As shown in Figure 1, light AO with an incident angle of 20 ° on the plane mirror. If the plane mirror is turned clockwise by 5°, the angle between the reflected light and the incident light is ____.
