人眼可见光的光谱结构（波长范围为 380 至 780 纳米的电磁波谱）被感知为颜色。白光是所有颜色的总和。如果用三棱镜将白光的所有成分（即不同波长的光）分割开来，那么这些波长的光就会呈现出彩虹的颜色。

The spectral structure of light visible to the human eye (an electromagnetic spectrum with a wavelength range of 380 to 780 nm) is perceived as color. White light is the sum of all colors. If all the components of white light (that is, the different wavelengths) are split by a prism, then the wavelengths appear as the colors of a rainbow.
