Someone says it lets us see better Hunan, someone says it is very magical very fast, even the speed that someone says it can let a person pass through time and space. What thing be such mystery? It is smooth.
有人说它让我们看得更清楚，有人说它很神奇很快，甚至有人说它的速度能让人穿越时间和空间。是什么东西如此神秘？它就是光。
Smooth speed is breathtaking, its speed can achieve every second to make an appointment with 300 million meters. If the whole world makes the supersonic speed aircraft with a very rapid rate jointly, it and light resemble a big tortoise following competition of train of in suspension of a magnetism than rising same. If you had velocity of light, so you run to be able to die immediately, the first, velocity of light is very fast, can allow you and air attrition even, make you burn directly; The 2nd, although you are not afraid of fire, that also cannot avoid to die, because velocity of light can let you have very big wallop, calculate you to bump to soft quilt, the freight car that you can have ten accelerator walk after all bumps in the feeling on your body at the same time to you, you do not perceive the possibility painful, because you lost consciousness on the spot.
光的速度是惊人的，它的速度能达到每秒约三十万千米。如果全球共同造一架速度非常快的超音速飞机，它和光比起来就像一只大乌龟跟一辆磁悬浮列车比赛一样。假如你拥有了光速，那么你跑起来会立刻死亡，第一，光速很快，甚至能让你和空气摩擦，使你直接燃烧；第二，即使你不怕火，那也无法避免死亡，因为光速会让你有很大的冲击力，就算你撞到柔软的棉被上，你都会有十几辆油门踩到底的货车向你同时撞在你身上的感觉，可能你感觉不到痛，因为你当场失去了知觉。
A lot of people think light is white, actual glazing is color, although light looks like white, but it is by red, orange, yellow, green, blue, indigo (cyanine) , violet 7 kinds of color comprise, use prism to be able to see, this also is the reason that why there is rainbow after rain, it is little water will smooth cent became rainbow.
很多人认为光是白色的，实际上光是彩色的，虽然光看起来像白色，但是它是由红、橙、黄、绿、蓝、靛（青蓝）、紫七种颜色组成的，用三棱镜就能看出来，这也是为什么雨后有彩虹的原因，是小水滴将光分成了彩虹。
Can not think this principle does lampion, some tubes are made by rare gas, so gas also can give off light.
你可别以为彩色灯都是这个原理做出来的，有些灯是由稀有气体做出来的，所以气体也能发光。
Light is so magical, is that light by what comprise? Light sheds composition by photon, but scientists had not discovered photon flows to be planted to Guang Mou up to now characteristic action, and how to comprise light.
光那么神奇，那光是由什么组成的呢？光是由光子流组成的，但是科学家们至今都还没发现光子流对光某种特性的作用，以及如何组成光。
The hope is in future, you can discover the secret about light.
希望在未来，你能发现关于光的秘密。
