By definition, color is the visible spectrum of light waves.

根据定义，颜色是光波的可见光谱。

Beyond the visible spectrum, our world is illuminated by invisible light.

除了可见光之外，各种不可见光也笼罩着这个世界。

This is what we call “visible light, ” also known as the visible spectrum.

这就是我们所说的“可见光”，又叫可见光谱。

And blue light has some of the highest energy wavelengths in the visible spectrum.

而蓝光在可见光光谱中具有最高能量的波长。

Electromagnetic radiation with a wavelength outside the visible light spectrum is invisible to our eyes.

在可见光谱范围之外的电磁辐射波长是肉眼看不见的。

And because this happens to every frequency in the visible spectrum, the combined color of all colors is white.

因为光谱里任何频率的可见光都会这样反射，所以所有颜色的光最后合起来成为白色。

Infrared can pass through human tissue more easily than some other wavelengths of light, like the visible spectrum or UV.

相比其他光的长波长，红外线更加容易的穿过人体组织，比如可见光谱或UV。

It includes ultraviolet at the far end of the non visible spectrum and three infrared bands at the other end.

它包括非可见光谱，一端是紫外线，另一端是三个红外线波段。

If you want to see all of the colors in the visible light spectrum, look no further than a rainbow!

如果你想看到可见光谱中的所有颜色，没有什么比彩虹更合适了。

This means it absorbs much of the visible spectrum, reflecting only red because red light is insufficiently energetic to shift the relevant electrons.

这意味着它吸收了大部分可见光谱，只反射红光，因为红光的能量不足以转移相关的电子。

They actively tune the spacing between nanoscale crystals in order to create structural colors that span the whole length of the visible spectrum.

间距，来制造跨越整个可见光谱上的颜色。在此我认为很了不起的一件事是我们认为我们很清楚。

Parker's wide field imager or WISPR caught the images in a pair of flybys observing the same visible spectrum our eyes can see.

帕克的宽视场成像仪或WISPR捕捉到了两次飞行的图像，观察到的可见光光谱与我们的肉眼所能看到的是一样的。

Like all mammals, we humans are only able to see light in the visible spectrum, which includes all of the colors of the rainbow.

和所有哺乳动物一样，我们人类只能看到可见光谱中的光，这包括彩虹的所有颜色。

Yet we know for a fact that those color frequencies outside our visible spectrum are there.

然而， 我们确实知道，可见光谱之外的那些颜色频率就在那里。

By looking at different parts of the visible and infrared spectrums, the two new telescopes will complement each other, says Magellan Telescope director Patrick McCarthy.

该望远镜的负责人帕特里克·麦卡锡表示通过观测可见光及红外线的不同部分，这两架新望远镜将进行优势互补。

The next step is to focus all of the visible spectrum into the same focal length using a meta-surface lens.

下一步是使用超表面透镜将所有可见光谱聚焦到相同的焦距。

Not to be confused with purple, which is just a combination of red and blue light, violet occupies a small portion of the visible light spectrum.

不要和紫色弄混，紫色是一种红光和蓝光的结合，而蓝紫色只在可见光光谱中占有很小的比例。

Three of them are in the infrared band as it were, outside the visible spectrum and one ultraviolet and they produce images which are not accessible to the human eye.

红外波段有三种，这些都是不可见光谱，还有一种紫外线，它们能显示出肉眼看不到的东西。

Each letter stands for a different wavelength on the visible spectrum, which correlates with a different color seen with the naked eye -- red, orange, yellow, green, blue, indigo and violet.

每个字母代表可见光谱上不同的波长，这与肉眼看到的不同颜色有关联——红色、橙色、黄色、绿色、蓝色、靛蓝和紫色。

Newton discovered long ago that all the colors we experience, the rainbow of the visible spectrum, are based on just a few wavelengths of electromagnetic radiation, which itself is, of course, entirely colorless.

牛顿很久以前就发现， 我们体验到的所有颜色，可见光谱中的彩虹， 都是基于电磁辐射的几个波长， 当然，电磁辐射本身是完全无色的。
