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.

当我们对量力学的理解还处于早期阶段时，一项新的发现提出，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.

量力学定律将这些电保持在原位，但如果将原暴露在或无线电波等电磁场中， 就会稍微扰乱电的方向。
