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.

当我们对子力学理解还处于早期阶段时，一项新提出，光既是子又是波。

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.

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， 就会稍微扰乱电子方向。
