An electron is confined inside a quantum dot, which for thisquestion can be approximated as a one-dimensional quantum box withrigid walls. The ground state has an energy of 0.042 eV.
(a) In your own words, explain why the energy of the groundstate of the system is larger than zero.
(b) Calculate the length of the quantum dot.
(c) What wavelength of photon is needed to cause a transition tothe next excited state?
(d) Is the wavelength of 2.958 μm observed in the spectrum ofthe quantum dot? Explain your answer.
