An electron is in a certain energy state in a one- dimensional, infinite potential well from x = 0 to x = L = 180 pm. The electron's probability density is zero at x = 0.300L, and x = 0.400L, it is not zero at intermediate values of x. The electron then jumps to the next lower energy level by emitting light. What is the change in the electron's energy?

An electron in a one-dimensional infinite potential well of length L has ground-state energy E_(1) . The length is changed to L' so that the new ground-state energy is E'_(1) = 0.500E_(1) . What is the ratio L'//L ?

An electron is confined to a tube of length L. The electron’s potential energy in one half of the tube is zero, while the potential energy in the other half is 10eV. If the electron has a total energy E = 15 eV , then the ratio of the deBroglie wavelength of the electron in the 10eV region of the tube to that in the other half is -
