11. (review) Let us consider the basic situation as depicted in Fig, 38-17 from the textbook. Does it become more or less likely that a particle will tunnel through the potential barrier if the following occur (assume ALL other parameters remain the same, only consider the effect of changing the one mentioned): a. Barrier height (Uh) is increased: b. Barrier width (L) is increased: c. Particle kinetic energy (E) is increased: (:1. Electron is replaced by proton with the same E: Classically, the electron lacks the energy to pass through the barrier region.
