Martin Jotov says the result is a light source that can be produced in mass quantities on a sheet of plastic.

马丁·乔托夫说，这带来的结果是人们可以在一片塑料上制造大量光源。

But today, you learned about how to analyze the composition of a light source using diffraction grating and spectroscopy.

但是今天，您了解了如何使用衍射光栅和光谱分析光源的成分。

A light source may be emitting an infinite number of rays, but we only draw a few to get the point across.

一个光源可以发出无限多的光线，但我们只需要几条就可以得到一个点。

This sort of low-energy focused white beam could be used for the very small — like a light source for microscopes — to the very big.

这种低能聚焦白色光束既可以应用于显微镜光源这种小物件上，也可以应用到大场合。

Insects do not fly directly toward a light source, but actually " tilt their backs toward the light, " said Sam Fabian of Imperial College London.

伦敦帝国理工学院的萨姆·法比安表示，昆虫不会直接飞向光源，而实际上是“背对着光源”。

And the next question is, can we easily trigger a light source so that every time we eat vegetables, it will go off?

下一个问题是， 我们是否可以轻松触发光源，以便每次吃蔬菜时它都会熄灭？

These rays are  called shadow rays because they determine whether a location is directly illuminated by  a light source or whether it's in a shadow.

这些光线称为阴影光线，因为它们确定某个位置是被光源直接照亮，还是位于阴影中。

They occur at the end of a massive star's lifespan, when a titanic explosion takes place, creating a light source which can easily outshine most of the stars around it.

超新星爆发是最具毁灭性危险的宇宙爆炸，它发生在巨大的星体到达生命末期时，这时会发生剧烈的大爆炸发出让周围多数恒星失色的强烈的亮光。

But if you have a light source with two wavelengths, then you'll get multiple sets of bright lines, whose color and locations will depend on the wavelength.

但是如果你有一个具有两种波长的光源，那么你会得到多组亮线，它们的颜色和位置将取决于波长。

If there are no objects between  the intersection point and a light source, then that means that this point on the blue stripe  is directly illuminated by that light source.

如果交点和光源之间没有物体，则意味着蓝色条纹上的该点被该光源直接照亮。

Then we calculate how that third point is directly illuminated using yet another set of shadow rays  thereby turning this third point into a light source that illuminates the previous point.

然后，我们计算如何使用另一组阴影光线直接照亮第三个点，从而将第三个点变成照亮前一个点的光源。

When we use our phones were staring directly into a light source and how much light falls onto a certain area like our eyes, usually measured in lux is dramatically impacted by our closeness to the device.

当我们使用手机时，我们直接盯着一个光源，光线落在某个区域（如我们的眼睛）上的量，通常以勒克斯（lux）为单位测量，会因我们与设备的距离而显著变化。
