Join Yahoo Answers and get 100 points today. Favorite Answer. what is the wave length of the first line of lyman series ? C. Can Bohr's explain why there are stable orbits without radiating any energy?… So, for your answer C, 1/wavelength = 1.096776X10^7 m^-1 (1/2^2 - 1/4^2), 1/wavelength = 1.096776X10^7 m^-1(0.25 - 0.0625), If you do the calculation for any of the other transitions, you will not get that same wavelength, 1/wavelength = 1.096776X10^7 m^-1 (1/4 - 1/25), and D gives 1/wavelength = 1.096776X10^7 (1/4-1/9).
