lambda = 7000; // Wavelength of the emitted light, angstrom
k = 8.6e-005; // Boltzmann constant, eV/K
dE = 12400/lambda; // Energy difference of the levels, eV
T = [300 500]; // Temperatures of first and second states, K
for i = 1:1:2
N2_ratio_N1 = exp(-(dE/(k*T(i)))); // Relative population
printf("\nThe relative population at %d K = %3.1e", T(i), N2_ratio_N1);
end
// Result
// The relative population at 300 K = 1.5e-30
// The relative population at 500 K = 1.3e-18
// The answer is given wrong in the textbook for first part.
