A real optical frequency comb spans the entire visible spectrum of light, and has very fine, evenly spaced teeth.

实际光学频率梳横跨整个可见光谱，各齿极细并均匀分布。

A new nanostructured material that absorbs a broad spectrum of light from any Angle could lead to the most efficient thin-film solar cells ever.

有一种新型纳米结构原材料，因其可吸收来自各个角度的广谱光源，能制成有史以来最有效的薄膜太阳能电池。

When the sun goes down the solar trees will return to their original position to give off a full spectrum of light to the street and pedestrians below.

日落后“太阳树”会回复到最初的位置，发出全光谱光线，为下面的街道和行人提供照明。

We can plug this in further when we're talking about the visible part of the light spectrum, because we know that for n final equals 2, then that would mean we plug in 2 squared here, so what we get is 1 over 4.

当我们讨论可见光谱的时候,我们可以把这个代进去,因为我们知道n末是等于2的,这意味着我们可以。

These give out a continuous spectrum of light, and thus affect a wide range of frequencies that are of interest to astronomers.

ECONOMIST: Going, going, nearly gone

The spectrum of light that emerges from such a container will show a series of dark lines interrupting what would be a continuous rainbow.

ECONOMIST: Fundamental physics

It could vaporize a rock and identify its minerals from the spectrum of light they emitted, or drill a sample and tease apart its chemical constituents.
