A) second line of Lyman series
B) second line of Balmer series
C) second line of Paschen series
D) an absorption line of Balmer series
Correct Answer: B
Solution :
Second line of Lyman series corresponds to the transition \[n=3\to n=1\] Second line of Balmer series corresponds to the transition \[n=4\to n=2\] Second line of Paschen series corresponds to the transition n = 5 to n = 3 An absorption line of Balmer series arises when electron jumps from n - 2 to any other higher state. Thus, choice (b) is correct.
