JEE PYQ: Atomic Structure Question 34
Question 34 - 2019 (10 Apr Shift 2)
The ratio of the shortest wavelength of two spectral series of hydrogen spectrum is found to be about 9. The spectral series are:
(1). (Lyman and Paschen)
(2). (Balmer and Brackett)
(3). (Brackett and Pfund)
(4). (Paschen and Pfund)
Show Answer
Answer: (1)
Solution
Shortest wavelength ratio: $\frac{\lambda_P}{\lambda_L} = \frac{n_{P}^2}{n_{L}^2} = \frac{9}{1} = 9$. Series are Lyman and Paschen.
