Success of classical free electron theory
WebThis theory is called quantum free electron theory. Classical free electron theory permits all electrons to gain energy. But quantum free electron theory permits only a fraction of electrons to gain energy. According to Quantum mechanics moving particles has some sort of wave motion Then wavelength λ=h/p (De-Broglie wavelength) Web11 Apr 2024 · According to classical free electron theory:A) There is no interaction between conduction and the interaction of electrons.B) The interaction of free electrons with ion cores is negligible.C) The free electron find uniform electric field of positive ions and that of electrons in metalD) All the above Questions & Answers JEE-MAIN Physics Grade 11
