Question

HW #11 (10pt) Q 1 . One - D imensio n al E nergy W ell (3pt) F igure a shows the energy - level diagram for a finite, one - dimensional energy well that contains an electron. The non - quantized region begins at E 4 = 450.0 eV. Figure b gives the absorption spectrum of the electron when it is in the ground state — it can absorb at the indicated wavelengths: λ a = 14.588 nm and λ b = 4.8437 nm and for any wavelength less than λ c = 2.9108 nm. What is the energy of the first excited state? Note that E 1 is the ground state. Q 2 . Three - D imensio n al E nergy W ell ( 3 pt) An electron (mass m )
