Then, the transducer uses the reflected waves to create an image.

然后， 换能器使用反射波创建图像。

And finally, we see the reflected waves of light from the statue.

最后，我们看到了雕像反射的光波。

That's where the reflected wave of light is not constructively interfering with itself.

这就是反射的 光波不会对其自身产生建设性干扰的地方。

But blue light has just the right wavelength: the reflected light waves are in sync, and that color makes it to our eye.

反射的光波是同步的，而这种颜色就进入了我们的眼睛。

The beauty of a spherical reflector is that, by changing the position at which you measure the reflected waves above the dish, you're measuring those waves from different parts of the sky.

球形反射器的美妙之处在于，通过改变测量盘上方反射波的位置，您可以测量来自天空不同部分的这些波。

If those layers are spaced out just right, we're talking a couple hundred billionth of a meter apart, certain colors of reflected light waves will interfere and only certain colors of light escape at certain angles.

如果这些层的间距恰到好处，我们说的是相隔几千亿分之一米，某些颜色的反射光波会干涉，只有某些颜色的光在某些角度能逃逸。
