Haryana Govt. The transitions are named sequentially by Greek letters: from n = 2 to n = 1 is called Lyman-alpha, 3 to 1 is Lyman-beta, 4 to 1 is Lyman-gamma, and so on. According to Bohr’s model, Lyman series is displayed when electron transition takes place from higher energy states(n h =2,3,4,5,6,…) to n l =1 energy state.
