This light is passed through a prism, which breaks it up into a spectrum, and a unique pattern, kind of like a chemical fingerprint of spectral lines for that element appears.

铁块会一直加热，直到到达某一燃点，便会辐射出光来；而当它的光线穿过一块棱柱时，棱柱就会分割光线，形成光谱。

And hydrogen atom is what we're learning about, so that's the most relevant here. But just to show you that each atom does have its own set of spectral lines, just for fun we'll look at neon also so you can have a comparison point.

为了给你们展示下每个原子，都有自己的一套谱线,仅仅是为了好玩，我们看下氖,你们可以比较一下。
