光的色散知识点(试题复习)
光的色散1．色散：白光分解成多种色光的现象。 2．光的色散现象：一束太阳光通过三棱镜，被分解成七种色光的现象叫光的色散，这七种色光从上至下依次排列为红、橙、黄、绿、蓝、靛、紫(如图甲所示)。同理，被分解后的色光也可以混合在一起成为白光(如图乙所示)。 光的三原色及色光的混合 1．色光的三原色：红、绿、蓝三种色光是光的三原色。 2．色光的混合：红、绿、蓝三种色光中，任何一种色光都不能由另外两种色光合成。但红、绿、蓝三种色光却能够合成出自然界绝大多数色光来，只要适当调配它们之间的比例即可。色光的合成在科学技术中普遍应用，彩色电视机就是一例。它的荧光屏上出现的彩色画面，是由红、绿、蓝三原色色点组成的。显像管内电子枪射出的三个电子束，它们分别射到屏上显不出红、绿、蓝色的荧光点上，通过分别控制三个电子束的强度，可以改变三色荧光点的亮度。由于这些色点很小又靠得很近，人眼无法分辨开来，看到的是三个色点的复合．即合成的颜色。 如图所示，适当的红光和绿光能合成黄光；适当的绿光和蓝光能合成青光；适当的蓝光和红光能合成品红色的光；而适当的红、绿、蓝三色光能合成白光。因此红、绿、蓝三种色光被称为色光的“三原色。”
物体的颜色：在光照到物体上时，一部分光被物体反射，一部分光被物体吸收，不同物体，对不同颜色的光反射、吸收和透过的情况不同，因此呈现不同的色彩。 光的色散现象得出的两个结论： 第一，白光不是单色的，而是由各种单色光组成的复色光；第二，不同的单色光通过棱镜时偏折的程度是不同的，红光的偏折程度最小，紫光的偏折程度最大。 色光的混合：不能简单地认为色光的混合是光的色散的逆过程。例如：红光和绿光能混合成黄光，但黄光仍为单色光，它通过三棱镜时并不能分散成红光和绿光。 物体的颜色： 由它所反射或透射的光的颜色所决定。 1．透明物体的颜色由通过它的色光决定在光的色散实验中，如果在白屏前放置一块红色玻璃，则白屏上的其他颜色的光消失，只能留下红色，说明其他色光都被红玻璃吸收了，只能让红光通过，如图所示。如果放置一块蓝玻璃，则白屏上呈现蓝色。 2．不透明物体的颜色由它反射的色光决定在光的色散实验中，如果把一张红纸贴在白屏上，则在红纸上看不到彩色光带，只有被红光照射的地方是亮的，其他地方是暗的；如果把绿纸

多彩的光知识点总结
《多彩的光》知识点总结 总结人:汪老师 总结日期：2015年1月26日 1、光源： 光源：自身能发光的物体叫做光源。 分类：自然光源、人造光源 2、光的直线传播 （1）条件：光在同种均匀介质中是沿直线传播的。 （2）光线：在物理学中，用一条待箭头的直线表示光的传播路径和方向，（光线是人们为了研究方便假想的一种物理模型，不是实际存在的） （3）光沿直线传播形成的现象：影子的形成、日食、月食、小孔成像 小孔成像的特点：倒立的实像。 注：小孔所成的像的形状跟物体的形状一样，与小孔的形状五无关，可以有缩小的、放大的和等大的像。 （4）光速：光在真空中传播速度最快，在其他介质中的传播速度都比在真空的速度小。 光在真空或空气中的传播速度是3×108m/s, 3、光的反射： （1）定义：光从一种介质射到另一种介质表面时，有一部份光被反射回原来的介质。 所有物体的表面都可以反射光，我们能够看到本 身不发光的物体，就是因为物体表面反射的光进入了 我们的眼睛。 （2）光的反射光路图： 入射光线：AO 反射光线：OB 法线：NO 入射角：∠i 反射角：∠r （3）光的反射定律：共面，异侧，等角 光在反射时，反射光线、入射光线与法线在统一平面内；反射光线和入射光线分别位于法线的两侧；反射角等于入射角，在光的反射中光路可逆。 注：一条反射光线对应一条入射光线 （4）反射分类：
镜面反射：平整光滑的物体表面能把平行的光线也沿平行的方向反射出去。 漫反射：一般物体的表面都很粗糙，存在许多微笑的凹凸不平，平行光线经反射后，反射光线不再平行，而是射向各个方向。 注：无论是镜面反射还是漫反射，每一条反射光线都遵守光的反射定律。 （5）平面镜成像： 成像原理：光的反射 成像特点：等大、对称的虚像 应用：1、改变光的传播方向（潜望镜）； 2、利用平面镜 成像。 4、光的折射 （1）折射现象：光从一种介质斜射如另一种介质时，传播方向发生改 变的现象。 （2）光的折射规律： 光折射时，折射光线、入射光线、法线在同一平面内，折射光线和入射光线分别位于法线的两侧。折射角随着入射角的改变而改变：空气中的角总是大角。 当光从一种介质垂直射入另一种介质时，传播方向不改变。光在折射时，光路是可逆的。（3）光的折射产生的现象：插入水中的筷子看起来便弯折了、海市蜃楼、在岸上看水中的鱼在水中的位置变浅了、游泳者从水中看岸上的树变高了。 5、光的色散：太阳光经过三棱镜折射后被分成红、橙、黄、绿、蓝、靛、紫七种颜色的光的现象。 （1）光的色散说明：白光不是单色光，而是由各种色光混合而成的。 光的“三基色”：红、绿、蓝。 颜料的三原色：红、黄、蓝。 （2）物体的颜色： 透明物体的颜色：透明物体的颜色由它透过的色光决定的。无色的通明体能透过所有色光。 不透明物体的颜色：不透明物体的颜色是由它反射的色光决定的。白色物体反色各种色光，黑色物体吸收所有色光。 6、透镜

(完整版)初二光学知识点整理
光学知识点知识点整理 一、光的直线传播 1、光现象：包括光的直线传播、光的反射和光的折射。 2、光源：能够发光的物体叫做光源。 ●光源按形成原因分，可以分为自然光源和人造光源。 例如，自然光源有太阳、萤火虫等，人造光源有如蜡烛、霓虹灯、白炽灯等。 ●月亮不是光源，月亮本身不发光，只是反射太阳的光。 3、光的直线传播：光在真空中或同一种均匀介质中是沿直线传播的，光的传播 不需要介质。 大气层是不均匀的，当光从大气层外射到地面时，光线发了了弯折（海市蜃楼、早晨看到太阳时，太阳还在地平线以下、星星的闪烁等） 光沿直线传播的现象：小孔成像、井底之蛙、影子、日食、月食、一叶障目。 ●光沿直线传播的应用： ①激光准直. 排直队要向前看齐. 打靶瞄准 ②影的形成：光在传播过程中，遇到不透明的物体，由于光是沿直线传播的，所 以在不透光的物体后面，光照射不到，形成了黑暗的部分就是影。 ③日食月食的形成 日食的成因：当月球运行到太阳和地球中间时，并且三球在一条直线上，太阳光沿直线传播过程中，被不透明的月球挡住，月球的黑影落在地球上，就形成了日食. 月食的成因：当地球运行到太阳和月球中间时，太阳光被不透明的地球挡住，地球的影落在月球上，就形成了月食. 如图：在月球后 1的位置可看到日全食， 在2的位置看到日偏食， 在3的位置看到日环食。 1 3 2
④小孔成像：小孔成像实验早在《墨经》中就有记载小孔成像成倒立的实像， 其像的形状与孔的形状无关。像可能放大，也可能宿小。 用一个带有小孔的板遮挡在屏幕与物之间，屏幕上就会形成物的倒像，我们把这样的现象叫小孔成像。前后移动中间的板，像的大小也会随之发生变化。 这种现象反映了光沿直线传播的性质。 小孔成像原理：光在同一均匀介质中，不受引力作用干扰的情况下沿直线传播根据光的直线传播规律证明像长和物长之比等于像和物分别距小孔屏的距离之比。 4、光线：用一条带有箭头的直线表示光的径迹和方向的直线。（光线是假想的， 实际并不存在） 光线是由一小束光抽象而建立的理想物理模型，建立理想物理模型是研究物理的常用方法之一。 5、光速：光在不同物质中传播的速度一般不同，真空中最快. (1)光在真空中速度C=3×108m/s=3×105km/s；光在空气中速度约为3×108m/s。 光在水中速度为真空中光速的3/4，在玻璃中速度为真空中速度的2/3 。 雷声和闪电在同时同地发生，但我们总是先看到闪电后听到雷声，这说明什么问题？ 这表明光的传播速度比声音快. (2)光年是长度的单位，1光年表示光在1年时间所走的路程，1光年＝3×108 米/秒×365×24×3600秒＝9.46×1015米 注意：光年不是时间的单位。 二、光的反射 1.反射：光在两种物质的交界面处会发生反射。 我们能够看见不发光的物体，是因为物体反射的光进入了我们的眼睛。 定义：光从一种介质射向另一种介质表面时，一部分光被反射回原来介质的现象叫光的反射。任何物体的表面都会发生反射。 2.探究实验：探究光的反射规律 【设计实验】把一个平面镜放在水平桌面上，再把一张纸板ENF竖直地立在平面镜上，纸板上的直线ON垂直于镜面，如图2-2所示。 一束光贴着纸板沿着某一个角度射到O点，经平面镜的反射，沿另一个方向
