Solution
The correct options are
A The line 2 represents a transition from quantum state n = 3 to n = 2
B The line 5 represents the one with second smallest wavelength
D Line 3 belongs to balmer series
By computing the energy differences between the sates, we can say lines 4, 5, and 6 belongs to Lyman series. Lines 2 and 3 are the first two lines of Balmer series and line 1 is the first line of Paschen series.
Line 2 belongs to Balmer series, and it represents the transition from n = 3 to n = 2 because it has the least energy released.
Line 5 has the second largest frequency, so it has the second smallest wavelength.
