QUESTIONS A hydrogen atom emits light and ends in a state characterized by n2 = 2. If the wavelength of the light emitted is 656 nm, use the Rydberg formula below to find the value of n that characterizes the initial state of the atom (RH=1.09737316* 107m-1) QUESTION 10 Consider a proton (m = 1.6726219 * 10-27 kg) confined in a box of length 2.000 pm. What is the energy difference between the n=1 and n = 2 states of the proton-in-a-box? Report your answer in units of 10-18 J (that is, if the energy is 5,00 x 10-18 J, you would report it as "5.00") Amate QUESTION 11 It can be shown that the maximum in the wavelength distribution for blackbody radiation can be approximated well by the formula hc 4.965 kg where h = 6.62607015* 10-34 J:sec, kg = 1.38068 * 10-23 JK, and C = 2.99792458 x 108 m/sec, Tis in K, and Amoxis given in m (a) If you have a normal body temperature of 40C, what is the value of Amax in the radiation that you emit? Report your answer in nm. and be careful of the units for temperature, x QUESTION 15 The energies in a 2D particle-in-a-box are given by h? (0, +0,) hany? in which the box is a square enclosure with Lx = Ly - L, and ny ny = 1,2,3,..... (a) If the particle is an electron and L = 200 pm (assume three significant figures), find the value of the lowest energy level in units of 10-18 (that is, if the energy is 5.00 * 10-18 J, you would report it as "5,00"). En ny Bre? QUESTION 17 The quantum numbers for several eigenstates are listed below. Match each with its degeneracy Be careful, and note that states like (2,9) and (6,7) are also degenerate for this system! . (1.2) A 2 (22) 3.1 . (3,5) : (1,7) 0.3 E5 C4
