Either a body absorbs light, or it reflects or refracts it, or does all these things . 一个物体不是吸收光就是反射或折射光,或是二者兼备。
It is assumed that the emission and absorption of light energy by an atom or molecule is not a continuous process but occurs in steps . 假定原子或分子发射光能和吸收光只能不是一个连续的过程,而是阶梯式发生的。

In particular , he realized that atoms can become excited ? that is , jump to a higher energy level ? if they absorb light 特别是他了解到原子在吸收光之后可以变成激发状态(也就是跳到较高的能阶) 。
