他解释了为什么颜色总是同样序列，因为光线折射以及水滴的反射。
He explains how the colors always appear in the same order because of how light refracts and reflects in the water droplets.
我利用不同颜色的光照射晶体，冰晶结构就像复杂的棱镜一样将光线折射到不同的方向。

这种虾能看到12种颜色，而人类只能看到3种，而且这种虾能够辨别不同形式的光线，并构成复杂而生动的3d图像。
The shrimps can see in 12 colours - humans see in only three - and can distinguish between different forms of light to give a sophisticated and vivid 3d image.
另外，内置传感器可在可视光谱与似乎红外光谱下探测到光线，计算机通过分析传感器的数据后便能够决定每个物件的颜色、类型、形状与位置。
By analysing data from a sensor that detects light in both the visible and the near-infra-red spectrum, a computer is able to determine the colour, type, shape and position of each item.
然后利用一些特殊颜色的光线使特定的细胞和回路活跃起来或者保持安静，借此他们可以发现这些细胞和回路在更大范围的神经系统中所扮演的角色。
They can then use specific colors of light to activate or silence particular cells and circuits, which in turns reveals the role that those cells and circuits play in the broader nervous system.
生物钟可以区分不同的颜色的，或者说，不同波长的光线。
The circadian clock can distinguish between different colors, or wavelengths, of light.
虽然太阳光看起来是白色的，但实际上它是多种颜色的光线的组合，其中就包含有蓝光。
Although the light from the sun looks white, it is actually a combination of many colors, including blue light.
当所有颜色可见光波达到反射强度时，物体表面就呈现白色；当最红的光线被吸收时，反射的影像就带有青色的色调。
When all these visible wavelengths are strongly reflected, the surface looks white; when the reddest light is absorbed, the reflection takes on a cyan tinge.
但鲨鱼缺少圆状细胞，这种细胞可以对不同波长的光线分别作出反应。在人类的眼睛里，各种各样的圆状细胞帮助我们分辨颜色。
Yet the sharks lacked cone cells, which respond individually to light at specific wavelengths. In human eyes, a variety of cone cells helps us to distinguish between colors.
顶点颜色和后面即将介绍的材质是不需要光线的，它们永远显示为定义好的颜色。
Vertex colors and, as you'll see later, textures don't need light; they will always display in the defined color.
如果鲨鱼的视网膜不能够分辨出不同颜色的光线，就如这项研究所述，那么他们很可能全都是色盲。
