LIGHT在英语中的意思是什么？

光

Light

光是辐射能量，通常是指人眼可见的电磁辐射，并且负责视觉。 可见光通常定义为波长在400纳米，或400×10-9米至700纳米的范围内，红外线与波长较长的紫外线，波长较短。 这些数字并不代表人类视觉的绝对限制，而是大多数人在大多数情况下可以看得到的大致范围。 各种来源将可见光定义为420至680微米，宽至380至800纳米。 在理想的实验室条件下，人们可以看到高达至少1050nm的红外线，儿童和年轻人的紫外线降至约310至313nm。 可见光的主要特性是强度，传播方向，频率或波长光谱和极化，而其在真空中的速度为299,792,458米/秒，是自然的基本常数之一。 可见光与所有类型的电磁辐射一样，通过实验发现在真空中始终以这种速度移动。

Light is radiant energy, usually referring to electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight. Visible light is usually defined as having a wavelength in the range of 400 nanometres, or 400×10−9 m, to 700 nanometres – between the infrared, with longer wavelengths and the ultraviolet, with shorter wavelengths. These numbers do not represent the absolute limits of human vision, but the approximate range within which most people can see reasonably well under most circumstances. Various sources define visible light as narrowly as 420 to 680 to as broadly as 380 to 800 nm. Under ideal laboratory conditions, people can see infrared up to at least 1050 nm, children and young adults ultraviolet down to about 310 to 313 nm. Primary properties of visible light are intensity, propagation direction, frequency or wavelength spectrum, and polarisation, while its speed in a vacuum, 299,792,458 meters per second, is one of the fundamental constants of nature. Visible light, as with all types of electromagnetic radiation, is experimentally found to always move at this speed in vacuum.

在英语 词典里light的定义

字典中光的第一个定义是照明的媒介，使得视觉成为可能。 光的其他定义也称为：可见光辐射。 能够引起视觉感觉并具有从约380到约780纳米的波长的电磁辐射。 光也是具有这个范围之外的波长的电磁辐射，尤其是紫外辐射。

Yehuda Amichai

I think the end is endless. It's either a big black hole or a big white light or both together. But it's totally meaningless, because even if someone would explain it, I wouldn't understand it.

2

Morena Baccarin

I've love to do more movies. Just because I'm interested in the medium very much. I've done a lot of theatre at this point, and I've done a lot of TV. I've done a few independent films, but a lot of them have not seen the light of day. It'd be really nice to be in a film that gets out there.

3

John Badham

In this movie they took them up in space. They're floating around and doing zero gravity stuff. Well, they had to do it all on wires. All the wires had to be painted black against this black background. If you didn't light it properly you could see the wires. Drove them crazy!

Nayvadius Cash

The hardest part of fame and success is adapting to the people around you that's changing. It changes the way people look at you from how they used to look at you. They listen to you on the radio, they look at you on TV and when people speak on you in a good light, you have a couple people who hold grudges.
