一束光

A spectrum is formed by a ray of light passing through a prism.

一束光通过棱镜就会形成光谱。

Each burst of the light cauterizes several exposed blood vessels.

每一束光可灸烧几条暴露的血管以消毒。

A square of light shone down on them from the open hatch.

一束光从敞开的舱门那照在了他们身上。

It´s kind of like the way a lens magnifies a beam of light.

它是一种象一种能放大一束光的方法。

This is what you see when you break up a beam of light with a prism.

这就是你用棱镜分解一束光时所看到的东西。
