    Physics: emission spectrum and electron rejection

    I have attached two physical chemistry problems. The first deals with converting wavelengths to frequencies and the second deals with electrons being ejected. I am a little confuse on how to approach these problems. If you would include all work and a complete explanation it would be greatly appreciated. I will try to apply these principles to similar problems I still need to finish. Thank you.

    1. Suppose you have sample of gaseous H atoms that has been heated so that each of the first three energy levels (n =1, 2, 3) is populated. What lines in the emission spectrum (in mm) can be observed from this sample? Also convert each of these wavelengths into frequencies (s^-1).

    2. The work function for gallium is 4.32 eV. If you shine blue light on sodium metal, will electrons by ejected? [1 eV = (1.602 X 10^-19 C) (1 V = 1.602 X 10^-19 J]
