1. The problem statement, all variables and given/known data An electron with a total energy of Eo = 4.4 eV is in the potential well shown above. 1) Find the ratio of the wavelength in Region III to the wavelength in Region I. λ III / λI = 1.77 2) Given that the wave function of the electron vanishes at the left boundary of Region I, what is the maximum width dof Region I such that there are no other nodes in Region I? .29 nm 3)What is the minimum energy of an electron such that it can never escape the well in Region I? ???? eV 2. Relevant equations E=hf T= e-2bL b=√(2m(U-E)/ħ2) R= (K1-K2)2/(K1+K2)2 3. The attempt at a solution Originally i thought that i need to set the probability of the particle transmitting equal to zero. But e can never be zero. So then i tried setting the probability of the particle reflecting equal to 1 but that still didn't lead to anything. Am i missing an equation?
