Nearly everything we understand about the Universe comes from light emitted or reflected by objects.

我们对宇宙的理解几乎都来自于发射或反射的光。

Maybe you're thinking, " Okay nerd, why is OLED or organic light emitting diode such a big deal? "

也许你在想，" 好吧，书呆子，为什么 OLED 这么重要？"

Because the light emitted at this time is what we see as the cosmic microwave background today!

因为此时发出的光就是我们今天所看到的宇宙微波辅助背景！

They then compare this spectrum with a theory, based on calculations from first principles, of how magnetic fields effect light emitted by hydrogen.

然后，他们把测得的光谱与理论计算得到的结果进行了比较，这种理论是基于氢怎样产生磁场效应区域的第一原则得到的。

The blue light emitted by electronic devices makes us feel less sleepy.

This is light that organisms can emit for themselves.

这是生以为自己发出的光。

And that movement changes the color of the light emitted by the gas.

而这种运动改变了气发出的光的颜色。

Hydrogen atoms, for example, absorb light emitted by other masses of heated hydrogen.

例如，氢原子吸收 其他质量的加热氢发出的光。

The y-axis is the intensity of the light emitted, while the x is the wavelength or color.

y轴是发出光的强度，而x轴是波长或颜色。

The light emitted by the table lamp was soft and not very dazzling.

The light emitted is mainly x-rays, but it can sometimes include visible light.

发出的光主要是X射线，但有时也包含见光。

Many telescopes are designed to primarily capture visible light, which represents only a sliver of the spectrum of light emitted by stars and other celestial objects.

许多望远镜的设计主要是为了捕捉见光，而见光只是恒星和其他天所发出光谱的一部分。

So, they'll measure the spectra of light emitted by material blasted away by the supernova that created this particular GRB.

因此，他们将测量由这特定伽马射线暴的母超新星爆发所喷射质的辐射光谱。

By that I mean we can't continue to use inefficient street lighting equipment which enables a lot of the light emitted to escape upwards into the sky.

我的意思是，我们不能继续使用低效的街灯设备，让很多光线逸入天空。
