While we’re observing these stars, we can use a spectrometer, the device that separates wavelengths, to reveal the star’s absorption spectrum and its elemental composition.

观察这些恒星时，可以使用分计这种能分离波长设备来揭示恒星吸收谱及其元素组成。

The advantage of trichromy disappears in darkness when colors are hard to distinguish, But the spectrometer data showed that fruits still stand out against a leafy background because they reflect more light than leaves too and therefore look brighter.

三色视觉优势在黑暗中消失， 因为颜色难以分，但分计数据显示， 水果仍然能在树叶背景中突出， 因为它反射线比树叶多， 因此看起来更亮。
