Yellow 相关知识点: 试题来源: 解析 A。解析:根据光子能量公式E = hf(E是能量,h是普朗克常量,f是频率),在可见光中,频率越高能量越高。紫光的频率最高,所以紫光的能量最高。红光频率最低,能量也低。绿和黄的频率和能量都低于紫光,所以答案为A。
In addition, we highlight the promising co-production combination of this system with renewable energy or energy storage systems. This review can help introduce the potential of oxygen reduction electrochemical pro-duction of high-flux H2O2 to the commercial market. Plating current density ...

We revise the dynamical properties of a class of cosmological models where the dark sector interacts through an interacting term that changes sign during evolution. In particular, we obtain the critical points and investigate the existence and stability conditions for cosmological solutions, describing ra...
