Answer
The wavelengths are longer in the case of the finite well.
Work Step by Step
As we can see by comparing Figures 40.12a and 40.15a, the finite well wavefunctions have the same number of cycles as those in the infinitely-deep well, but these cycles are spread over a longer base. Therefore the wavelengths in the case of the finite well are longer.
Because the wavelengths are longer, the energies will be lower than the corresponding energies in the infinite well.
