(2)像、物到镜面的距离相等;(3)像、物的连线与镜面垂直;(4)物体在平面镜里所成的像是虚像。4.光的折射规律:在折射现象中,折射光线、入射光线和法线都在同一个平面内;光从空气斜射入水中或其他介质中时,折射光线向法线方向偏折(折射角<入射角);光从水或其他介质中斜射入空气中时,折射光线向界面方向偏折(折射角>入射角)。在折射现象中,光路是可逆的。在光的折射现象中,入射角增大,折射角也随之增大。在光的折射现象中,介质的密度越小,光速越大,与法线形成的角越大。5.凸透镜成像的规律:具体见下表。物距像的性质像距U与v关系应用对应图倒、正放、缩虚、实uu放大镜1U=f光线平行射出,不成像2f2fu2f倒立缩小实像fv照相机5二、记住光学常数一、光学的五个规律1.光的直线传播规律:光在同一种均匀透明介质中是沿直线传播的。2.光的反射定律:(1)反射光线与入射光线、法线在同一平面上;(2)反射光线和
