In the Lyman series of hydrogen electron energy transitions, the lower energy state is the ground state (n= 1). If the upper state is the second excited state (n= 3), this produces a line called ‘Lyman beta’ whose transition is depicted in Figure 2. In the Balmer series of hydrogen electron energy transitions, the lower energy state is the first excited state (n = 2). If the upper state is the second excited state (n = 3), this produces a line called ‘Balmer alpha’ whose transition is also depicted in Figure 2. Which of the following statements are true about these two lines? Choose all that apply.
