(a) According to classical mechanics, a particle would never be able to pass-through or penetrate through a potential barrier with energy greater than the particle. However, quantum mechanics predicts that it is possible under certain conditions. Explain with necessary diagram and equation [5] (b) A beam of electrons is incident on a potential barrier of height 10eV and width 10 nm. What should be the energy of electron so that half of them are able to penetrate through the barrier. [5]
