[领域] (题目相关领域) 近代物理 [来源] (课本习题、考古题、参考书...) 作业题目 [题目] Recall that the transmission amplitude at a potential step is t=2k/(k+k') 1 t ----> ----> ______ r<---| __k____| k' In the problem illustrated, k'<k, which makes t>1 Explain how the transmitted amplitude can be greater than the incident amplitude. [瓶颈] (写写自己的想法，方便大家为你解答) 我只会导公式导到题目上所写的方程式 但是我发觉我解释不出来老师的问题 --
