These two combined light rays also cause us to see yellow.

这两种结合的光线也使我们看到黄色。

Anything black absorbs most of the light rays that fall on it.

任何黑色的东西吸收了大部分照在其上的光线。

This again causes light rays to be focused in front of retina.

会再次导致光线聚焦在视网膜前面。

The gravitational deflection focused light rays that were initially diverging onto paths that converged at the Earth.

引力透镜使得本来会发散的光芒聚焦在地球上。

As when objects come closer than 6 meters, light rays start to diverge, changing their focus.

当物体接近 6 米时，光线开始发散，改变焦点。

Spp means samples per pixel, so this the number of light rays we compute for every pixel.

Spp 表示每像素的样本数，也就是我们计算的每像素的光线数量。

Each member of the expedition was required to bathe regularly in the light rays of these lamps.

探险队的每个队员都被要求定期在这些灯的光线中沐浴。

That's an enormous amount of data about the color, brightness and direction of all light rays within a frame.

这可是在成像区域内对于颜色、光强以及所有光线反射等海量的数据信息。

Light rays too must follow geodesics in space-time.

光线也必须遵循时空中的测地线。

Astonishingly, Leonardo already knew from his optic studies that light rays do not come to a single point in the eye.

令人惊讶的是，列奥纳多已经从他的光学研究中知道光线不会到达眼睛的单个点。

Curvature; increase of curvature of cornea or lens causes light rays to be focused in front of retina and hence Myopia occurs.

曲率；角膜或晶状体曲率的增加会导致光线聚焦在视网膜前方，从而发生近视。

Axial; increase in axial length of eye increases the converging power and cause light rays to be focused in front of retina.

轴向；眼轴长度的增加会增加眼球的辐合能力，使光线聚焦在视网膜前面。

Suddenly I realized that the paths of these light rays could never approach one another.

我突然意识到，这些光线的路径永远不可能相互接近。

Mirrors also change the direction light travels, and if you used a curved mirror you can also bring light rays to a focus.

单面镜也可以改变光的传播方向，如果你使用曲面镜，你还可以让光线汇聚到一个焦点。

The objective lens takes incoming light rays from a distant source. .

物镜从远处接收入射光线。

Here’s how it works: The objective lens takes incoming light rays from a distant source.

它的工作原理是这样的：物镜从远处接收入射光线。

That’s the distance at which parallel light rays converge after passing through a converging lens.

这是平行光线通过会聚透镜后会聚的距离。

That's the distance at which parallel light rays converge after passing through a converging lens.

这是平行光线 通过会聚透镜后会聚的距离。

Now, you can measure a lens’ magnifying power by comparing the angles at which light rays enter your eyes.

现在，您可以通过比较光线进入眼睛的角度来测量镜头的放大倍数。

The objective lens then converges the light rays to form a real, flipped image inside the telescope.

然后物镜会聚 光线，在望远镜内部形成一个真实的翻转图像。
