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 -
