N-COUNT A prism is a block of clear glass or plastic that separates the light passing through it into different colours. 棱镜
N-COUNT a polyhedron having parallel, polygonal, and congruent bases and sides that are parallelograms 棱柱体 [maths]
Light is refracted when passed through a prism.
光通过棱镜时产生折射。
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。
This light is passed through a prism, which breaks it up into a spectrum.
这种光通过棱镜,而棱镜把它分割成了一道光谱。
There it is. He used the prism spectrograph to analyze his results. So what do we have here?
在这里,他用了棱镜分光图来分析他的结果,得到些什么呢?
And then he just takes that narrow column of light and he admits it to a prism. And what the prism does is takes a tiny, tiny difference in wavelength and refracts it through a different angle.
他只取了那个窄光柱,然后把它对准一个棱镜,棱镜所做的就是,测量出波长的细微差别,然后从不同的角度测定它的折射度。
And if the prism is of sufficient dimension that angle can be magnified.
如果这个棱镜有多个面,可以把角度也放大。
