Introduction
按照物理学的发现,电磁辐射通常知道的所有方面的光。然而,人眼可以发现只有一小部分的电磁波谱。人眼由锥形细胞是负责做这个电磁波谱可见。基于这样的范本,物理,本教程将包括可见光光谱的解释。
What is the visible spectrum of pght?
Figure 1: Visible pght spectrum
可见人类的眼睛是电磁波谱的一部分称为可见光谱。光通常被定义为电磁辐射主要是检测到的人眼或可见。
它已经观察到,人类的眼睛是发现敏感不同,不同波长的光谱。按照信息的范围波长所认可的人类的眼睛是380至700纳米(美国国家航空航天局,2022年)。
这一特定光谱的可见光不包含所有的颜色,所有的颜色并不区分了人类的眼睛。实例,光谱中红色缺失的存在是超出人眼的检测能力。
Wavelength and colour spectrum chart
物理学的术语,如频率和能源股电磁波谱与波长的关系密切。这一现象被认为是负责任的属性的颜色辐射的决心。在电磁波谱的规模,呈现两种颜色之间的界限不明显,显然彼此分离,而色彩是彻底混合(风扇et al . 2019年)。
这个原因的颜色带可见光谱,紫外区域被确定在一个边缘而红外辐射标识放置在另一个乐队的边缘。在可见光谱中,每个波长是由一个特定的颜色。每种颜色由不同的特点和波长是不同的。
Colour and Temperature
根据物理定律,温度将检测的对象越多,更短的波长会。这是根本原因,肉眼可以观察到的变化颜色的白光通过棱镜。例如,打击火炬的火焰可以被视为转移按照颜色从红色到蓝色1基于温度的调整(Researchgate网站,2022)。这是原因,帮助科学家马克的温度与热恒星的恒星大气将决定不同波长的光在比较凉爽的。

最常见的一个方面的电磁频谱的光就是电磁波有能力通过规范或真空。这一现象的主要原因是,电磁波可以通过外太空的真空传输能量。电磁波的产生可能是由磁性的振动或震动的指控(Researchgate网站,2022)。
因此,电磁频谱包含一个广泛的频率和波长。为了研究,整个可见光谱通常是分解成小的特定部分。这个隔离可以做基于观察,它出现的方式;的电磁波与物质相互作用的方式。

按照电磁频谱反映在星星遥远的主要介质测量的温度特别的明星。例如,它可以表示,太阳表面的温度水平的5800 k(美国国家航空航天局,2022年)。这是原因,阳光的峰值波长约为550纳米。它将红色如果的温度和冷却相比,目前的测量温度。另一方面,如果太阳热,它将出现在蓝色的颜色。
Conclusion
当前教程已经阐明定义视觉光谱的概念通常指的是特定波长的电磁波谱可能被人类的眼睛。本教程讨论进一步包括基于波长和白光的色谱图只能看到当光穿过棱镜。已经看到,每一个光的光谱波长的不同。基于此波长光谱定义了他们的位置在seven-coloured图表由光的折射和色散。
FAQs
Q1。电磁波谱的多少是由可见光吗?
光可能前往我们的眼睛是不到1%的可见光谱。按照科学家,测量代表总数的0.0035%磁谱作为人类的眼睛被认为是有限的范围。
Q2。是什么定义的短语:电磁波谱?
白光通常由七种不同的灯光不同的波长。这场音乐会之后,电磁频谱被定义为整个电子辐射分布按照波长或频率
第三季。可见光是什么?
按照物理学的发现,美元mathrm{400:太赫兹::800:太赫兹:}美元被认为是频率的可见光。光与不同频率不超过美元mathrm{: 700: 400:纳米纳米:}$可以区分人眼的光学。这是主要的原因,使光学可见的光。
第四季度。波长的电磁能量是可见的人眼?
可感知的部分电磁波谱的人类的眼睛是公认的可见光谱。的波长范围,可以检测到人类的眼睛被称为范围从330到700纳米。
