Then she was able to capture the sharp difference between light and dark.

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 what we predict as an energy difference between two levels, we know should correspond to the energy of light that's either emitted, if we're giving off a photon, or that's absorbed if we're going to take on a photon and jump from a lower to a higher energy level.

我们预测，两个能级之间的能量差，我们知道，它要么和发出的光有关,如果它发出光子的话，要么它吸收光子,从低能级跃迁到，更高能级上去。

And Einstein credited de Broglie, which is a fair statement of lifting a corner of the great veil, because really there was this fundamental misunderstanding about what the difference was between matter and light, and the reality is that they can both be like-particles and they can both show characteristics of waves.

并且爱因斯坦相信德布罗意，他做了一个公正的论述,揭开了一个伟大面纱的一角，因为关于物质和光,以前确实存在着,根本性的误解，真实情况是它们同时,具有粒子和波的特性。
