The formula relating energy of a photon to its wavelength is E = hc/lambda where E = energy, h = Planck's Constant, c = speed of light.
Use the formula for energy of the different levels to figure out the energy associated with those transitions. Since this is an exam, I'll assume you studied that formula or it's in front of you. I'm not going to cheat on a test.
