the question states that the emission spectrum of hydrogen contains a line with wavelength 656.2nm. and we need to approx find out what temp the H gas needs to have to be heated before this line appers in the spectrum
i have worked out that for this wavelength the electron mov from level 3 to 2, and that the energy between these two levels is ~1.89ev (3.03E-19 J)
im not sure whether i can use the internal energy formula = 1/2(RfnT) = 1/2(3RT)
or the weins law for blackbodies => lamda = 2.898E-3/T
