Well, a natural place to start, where quantum mechanics itself started, is light.

好吧，一个自然的起点，量子力本身也是从这里开始的，就是光。

When our understanding of quantum mechanics was in its early stages, a new discovery proposed that light acts as both a particle and a wave.

对量子力的理解还期阶段时，一项新的发现提出，光既是粒子又是波。

The laws of quantum mechanics keep these electrons in place, but if you expose an atom to an electromagnetic field such as light or radio waves, you can slightly disturb an electron's orientation.

量子力定律将这些电子保持在原位，但如果将原子暴露在光或无线电波等电磁场中， 就会稍微扰乱电子的方向。
