Introduction
光由一种电磁波(EMW)表示,在那里,它的传播,同时振荡电场和磁场强度。在这里,将电场垂直于磁场,反之亦然。不仅如此,这两个组件一起摆动垂直于传播方向的光波。
主要由于电场振荡的一架飞机被认为是光作为电磁波磁场相比。因此,光的电磁波也称为横向波。自从原子产生EMW可以在各个方向振动或摆动,很难集中一个点我们需要的光。对于某些应用程序光的强度应该减少车辆,防止事故一样,不应该有明亮的光线反射回来。
DECHAMMAKL, Electromagnetic waves, CC BY-SA 4.0
克服这类问题,光波强度的亮度应该减少启动原子各方向摆动,从而使光波传播只在一个方向上。这个过程称为极化,它是通过使用宝丽来完成的。
What is Polarization?
我们知道光明是一个横电磁波的电场的性质是它垂直于传播光传播在一个平面上。粒子在不同方向的光振动,引起电场的振动组件在振动方向在一个平面上。在正常光线,电场的振动将在不同的方向导致unpolarised光。假设我们约束的所有振动电场除向一个方向,每个方向,据说偏振光和获取偏振光的这个过程称为极化。

Types of polarisation of pght
线性极化
圆偏振−相同振幅和相位差90度。
椭圆极化−不同振幅和相位差90度。
What are Polaroids?
偏振的光可以通过非偏振光穿过一层很薄的晶体材料。这种薄晶体材料被称为偏光板或偏振器。张照片的分子定位在一个特定的方向,据说是轴的偏光板,这有助于在只允许这些振荡电场是符合这个轴。因此,产生偏振光。
What are Polaroid Films?
宝丽来的电影是由有机材料组成的长链分子或原子在一个特定的方向一致的。在宝丽来的电影,晶体材料分子放置两个玻璃样的表之间的物质。在宝丽来的电影,我们考虑的是水晶材料硫酸奎宁或herapathite放置两个透明的硝基聚合物之间的电影。这些晶体是一致通过施加电场或磁场在一个特定的方向给张照片的轴。
How pght is polarized using polaroid film?
当一个非偏振光有横向电场振荡在各个方向穿过宝丽来胶片,朝一个方向偏振光波振荡会传播的宝丽来。传播方向的偏振光的方向取决于晶体内的原子或分子的排列宝丽来胶片。这有助于降低强度或亮度的光用于许多应用程序。如果$ mathrm {I_{0}} $的强度是一个非偏振光通过宝丽来的电影,然后从宝丽来将透射光强度即假设偏振光的方向之间的角度的轴线宝丽来美元mathrm {heta} $,那么透射波的振幅将美元mathrm {Ecos: heta} $。这里E是电场分量的振幅。然后之间的关系强度的非偏振光传播偏振光强度根据马陆的法律,
$ $ mathrm {I = I_{0}因为^ {2}heta} $ $
The direction of Polarization of Light
光的偏振方向只是振荡后的电场极化的方向。非偏振光,电场振荡四面八方可以转化为偏振光,电场振荡的只在一个方向上。这个过程只允许一个方向的EMW是通过使用人造偏光板。因此,宝丽来速拍照片可以控制光传播的方向。这意味着传播方向的偏振光将宝丽来的方向轴在电影。

戴着墨镜减少有害太阳光落在我们的眼睛。
在汽车车灯控制光的亮度有助于减少事故的发生。
在摄像机获取better-colored图片。
在火车与飞机玻璃窗,宝丽来电影帮助减少明亮的光通过强度。
FAQs
Q1。有哪些不同的方法对偏振光线除了光板?
Ans。光的极化可以被另一个进程获得的光散射、光反射和尼科耳棱镜。
Q2。什么是宝丽来的二向色性物质?
Ans,宝丽来速拍照片,二向色晶体,这意味着这些类型的物质只允许某一特定方向上的振动波和吸收剩余的。
这个过程的物质选择一个方向波传输通过叫做二色性和这些物质被称为二向色性物质。
第三季。有任何有机材料极化光自己?
Ans。是的,液晶是有机材料可以极化光和传输,因为所有液晶中的分子会专门在一个方向上保持一致。
第四季度。人造偏光板的分析器是什么?
答。我们可以使用两个偏振器的过程中,光的偏振。分析仪作为第二偏振器,有助于找出是否第一偏振镜平面偏振的光传输。
Q5。解释偏振光偏振器和分析器是互相垂直吗?
答。假设偏振器轴平行排列,然后从非偏振光只允许这些振荡电场偏振器轴平行的方向。之后,如果我们把一个分析器,其轴是垂直地对齐,然后没有偏振光通过分析仪。这是因为偏振光偏振器的振荡平行。
