Calculate the ration of sodium atoms in the 3p excited to the number in the ground state at 2500 and 2600k { h= 6.6261 x JS, C = 2.998 x m/s, 1 nm = m, the statistical weights for the 3s and 3p quantum states are 2 and 6 respectively. Boltzmann’s constant k = 1.38 x .                                                  [2 ½ marks]
