Question

Total number of lines in Lyman series of H spectrum will be: (where n = no. of orbit)

• A. n
• B. n-1
• C. n-2
• D. n(n+1)

Answer 1

The correct option is B

n-1

Total number of lines in Lyman series is given by (n - 1).

For eg. If n = 4

Lyman lines obtained are 3 when n = 4. Hence, in general, no. of lines in Lyman series is (n - 1).
