The electrons within an atom of element"X" oscillate with a natural frequency 5.0X10‘14Hz.Would a medium made of element"X" be transparent or opaque light of frequency 5.0X10‘14Hz?
中文意思就是说一个物体的固有频率是5.0X10‘14Hz,问它可不可以让同频率的可见光穿过?为什么?
通常是不透光的,光会被吸收.尤其是半导体,意味着光子的能量和其能带宽度是对应的,因此能使价带中的电子跃迁到导带,balabala~总之就是光子的能量被吸收了,传递给了物体的电子.既然没有能量,光如何传播?但其实想的更simple点,共振频率一样,意味着物体的振动加强,对吧?那多余的能量哪里来,自然就是光子携带的能量,同样光子的能量被吸收,不能传播了.
