Figure 39-28a shows the energy-level diagram for a finite, one-dimensional energy well that contains an electron. The non-quantized region begins at E4 = 450.0 eV. Figure 39-28b gives the absorption spectrum of the electron when it is in the ground state-it can absorb at the indicated wavelengths: λa = 14.588 nm and λb = 4.8437 nm and for any wavelength less than λc=2.9108 nm. What is the energy of the first excited state?
