But instead of taking a single path, light can bend around the object in one of two, or four different routes, thus doubling or quadrupling the amount of information scientists receive.
但是光并非只走一条路径，而是可以从两个或四个不同路径中的一个绕过物体，这样科学家可以获得两倍或四倍的信息量。
Having a series of layers also helps to "bend" the flow of sunlight which assists in capturing light that would otherwise be reflected off.

In natural materials, light waves entering at an Angle always bend to plunge more steeply into the material-the hallmark of a refractive index greater than 1.
在自然物质中，以一定角度进入的光波，进入物质后的角度更小——标志着折射率大于1。
The light source will most likely determine where the highlights and shadows fall (although with Web design you can afford to bend these rules in places).
光源位置决定了高光和阴影的位置（不过在网页设计中你能打破这些规则）。
The unusually cold sea air caused light to bend abnormally downward, Maltin said.
马丁说，异常寒冷的海洋空气使得光线反常地向下弯曲。
All transparent substances slow down the light that moves through them — that's why light seems to bend, or refract, when it passes from air to water.
一切透明物质都会减缓通过它的光的运动速度——这就是为什么当光由空中进入水中时，光看上去似乎被弯曲或折射的道理。
"The beauty of this technology is that you can bend the light and use it to access areas that you otherwise couldn't," said Ellenbogen.
“这种技术的美妙之处在于你可以使光弯曲以到达原来不能到达的地方。”Ellenbogen说。
We have explained this being due to light in the red spectrum bending readily, so red light is bent first over the horizon by the gravity of Earth where light in the other spectrums is not so bend.
我们解释过这是由于红色光谱更容易弯曲，所以当其他光线还没怎么样时，红光首先由于地球的引力而沿着地球的曲线弯曲。
He worked out just how much the light would bend; he could also work out how far the stars would appear to have moved.
他把光的弯曲度计算了出来；他还能把星球看上去移动了的距离也计算出来。
Materials that corkscrew, bend, grow, and shrink in response to heat and other stimuli, such as light and electricity, have been around for decades.
早在几十年前，人们就发现材料遇热或受到其他刺激（如光、电）时会发生扭转、弯曲，扩展或收缩现象。
Use a mirror to bend sunshine to light up a corner where can't receive light directly.
用镜子把阳光反射到屋子里永远也见不到阳光的那个墙角。
A very massive object - such as a galaxy cluster - can bend and magnify light from galaxies behind it.
