It is also about diplomacy and promoting China’s soft power. In Moscow, Peng visited a boarding school for orphans and children away from their parents, encouraging them to struggle for a better life, which brought out the maternal side of her character. In Tanzania, she donated sewing machines and school bags to women and children.

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

初二物理光的色散知识点

初二物理光的色散知识点 物理的学习需要的不仅是大量的做题,更重要的是物理知识点的累积。下面就和丁博士一起来看看初二物理光的色散知识点,希望对广大考生有帮助! 1、光从一种介质斜射入另一种介质时,传播方向发生偏折。 2、光在同种介质中传播,当介质不均匀时,光的传播方向亦会发生变化。 3、折射角:折射光线和法线间的夹角。 光的折射定律 1、在光的折射中,三线共面,法线居中。 2、光从空气斜射入水或其他介质时,折射光线向法线方向偏折;光从水或其它介质斜射入空气中时,折射光线远离法线(要求会画折射光线、入射光线的光路图) 3、斜射时,总是空气中的角大;垂直入射时,折射角和入射角都等于0°,光的传播方向不改变 4、折射角随入射角的增大而增大 5、当光射到两介质的分界面时,反射、折射同时发生 6、光的折射中光路可逆。 光的折射现象及其应用 1、生活中与光的折射有关的例子:水中的鱼的位置看起来比实际位置高一些(鱼实际在看到位置的后下方);由于光的折射,池水看起来比实际的浅一些; 水中的人看岸上的景物的位置比实际位置高些;夏天看到天上的星斗的位置比星斗实际位置高些;透过厚玻璃看钢笔,笔杆好像错位了;斜放在水中的筷子好像向上弯折了;(要求会作光路图) 2、人们利用光的折射看见水中物体的像是虚像(折射光线反向延长线的交点) 1、太阳光通过三棱镜后,依次被分解成红、橙、黄绿、蓝、靛、紫七种颜色,这种现象叫色散; 2、白光是由各种色光混合而成的复色光; 3、天边的彩虹是光的色散现象; 4、色光的三原色是:红、绿、蓝;其它色光可由这三种色光混合而成,白光是红、绿、蓝三种色光混合而成的;世界上没有黑光;颜料的三原色是品红、青、黄,三原色混合是黑色;

(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

(完整版)光现象知识点总结(全)

第二章光的传播 一、光的传播 1、光源:能发光的物体叫做光源。 光源可分为天然光源(水母、太阳),人造光源(灯泡、火把); 月亮、钻石、镜子、影幕不是光源。 2、光在同种均匀介质中沿直线传播; 光的直线传播的应用: (1)小孔成像:像的形状与小孔的形状无关,像是倒立的实像(树阴下的光斑是太阳的像)。实像:由实际光线会聚而成的像。 ①小孔成像的条件:孔的大小必须远远小于孔到发光的距离及孔到光屏的距离。 ②像的大小与发光体到孔的距离和像到孔的距离有关,发光体到小孔的距离不变,光屏远离小孔,实像 增大;光凭靠近小孔,实像减小; 光屏到小孔的距离不变,发光体远离小孔,实像减小;发光体靠近小孔,实像增大。 (2)取得直线:激光准直(挖隧道定向);整队集合;射击瞄准; (3)限制视线:坐井观天、一叶障目; (4)影的形成:影子;日食、月食 日食:太阳月球地球;月食:月球太阳地球 常见的现象: ①激光准直。 ②影子的形成:光在传播过程中,遇到不透明的物体,在物体的后面形成黑色区域即影子。 ③日食月食的形成:当地球在中间时可形成月食。 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。 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 3、光线:常用一条带有箭头的直线表示光的径迹和方向;(是理想化物理模型,非真实存在) 4、所有的光路都是可逆的,包括直线传播、反射、折射等。 5、真空中光速是宇宙中最快的速度;c=3×108m/s=3×105 m/s; 6、光年:是光在一年中传播的距离,光年是长度单位;

声音在固体中传播得最快,液体中次之,气体中最慢,真空中不传播; 光在真空中传播的最快,空气中次之,透明液体、固体中最慢(二者刚好相反)。 光速远远大于声速(如先看见闪电再听见雷声;在跑100m时,声音传播时间不能忽略不计,但光传播时间可忽略不计)。 二、光的反射 1、当光射到物体表面时,被反射回来的现象叫做光的反射。 2、我们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。 3、反射定律:(1)在反射现象中,反射光线、入射光线、法线都在同一个平面内; (2)反射光线、入射光线分居法线两侧; (3)反射角等于入射角。(说成入射角等于反射角是错误的) (1)法线:过光的入射点所作的与反射面垂直的直线;(虚线) (2)入射角:入射光线与法线的夹角;(实线) (3)反射角:反射光线与法线的夹角。(实线) (4)反射角总是随入射角的变化而变化,入射角增大反射角随之增大。 (5)垂直入射时,入射角、反射角相等都等于0度。 4、光路图(要求会作): (1)、确定入(反)射点:入射光线和反射面或反射光线和反射面或入射光线和反射光线的交点即为入射(反射)点 (2)、根据法线和反射面垂直,作出法线。 (3)、根据反射角等于入射角,画出入射光线或反射光线 5、两种反射:镜面反射和漫反射。 (1)镜面反射:平行光射到光滑的反射面上时,反射光仍然被平行的反射出去; (2)漫反射:平行光射到粗糙的反射面上,光线向各个方向反射出去; (3)镜面反射和漫反射的相同点:都是反射现象,都遵守反射定律; 不同点是:反射面不同(一光滑,一粗糙),一个方向的入射光,镜面反射的反射光只射向一个方向(刺眼);而漫反射射向四面八方;(下雨天向光走走暗处,背光走要走亮处,因为积水发生镜面反射,地面发生漫反射,电影屏幕粗糙、黑板要粗糙是利用漫反射把光射向四处,黑板上“反光”是发生了镜面反射,光污染也是镜面反射) 6、潜望镜的工作原理:光的反射。 三、平面镜成像 1、平面镜成像特点:①正立的虚像, ②像和物的大小相等, ③像和物关于镜面对称(轴对称图形) ④像和物对应点的连线和镜面垂直,到镜面距离相等; ⑤像和物上下相同,左右相反(镜中像的左手是人的右手,物体远离或靠近镜面像的大小
