The types of gases in Earth's atmosphere mostly scatter the shorter, choppier waves of blue light.

地球大气中的气体类型主要散射较短的、起伏较大的蓝光波。

We register short waves at high frequencies as bluish colors, while long, low frequencies look reddish to us.

我们将高频的短波记录为蓝色，而长的低频在我们看来是红色的。

And when our eyes recognize the color blue, we're really seeing shorter, choppier light waves with peaks that are close together.

当我们的眼睛识别蓝色时，我们看到的是更短、更波峰接近的光波。

A high-pitched noise is the result of shorter waves moving in and out more quickly, while fewer, slower fluctuations result in a lower pitch.

高音调的噪音是较短的波更快地进出的结果，而较少、较慢的波动会导致较低的音调。
