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

嗯，个自然的起点，即量子力学本身的起点，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.

当我们对量子力学的解还处于早期阶段时，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.

量子力学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。
