A microscopic spring-mass system has a mass m = 4x10-26 kg and the energy gap between the 2nd and 3rd excited states is 6 eV. a) (3 Points) Calculate in joules, the energy gap between the 1st and 2nd excited states: AE1-2 = b) (3 Points) What is the energy gap between the 4th and 7th excited states: AE-7 = [ev] c) (3 Points) The energy of the ground state is: En [eV] d) (3 Points) The stiffness of the spring is: k, = [N/m] e) (3 Points) What is the smallest amount of vibrational energy that can be added to this system? E = [ev] f) (5 Points) What is the wavelength of the smallest energy photon emitted by this system? A = g) (3 Points) If the stiffness of the spring increases, the wavelength calculated in the previous part h) (2 Points) If the mass increases, the energy gap between successive energy levels Increases 2. decreases 3. the given in t sufficien i) (5 Points) What should the stiffness of the spring be, so that the transition from the 3rd excited state to the 2nd excited state emits a photon with energy 6.5 eV? k, = [N/m]
