SATHEE: Atoms And Nuclei Question 107

Atoms And Nuclei Question 107

Question: The first line in the Lyman series has wavelength l. The wavelength of the first line in Balmer series is [MH CET (Med.) 2001]

Options:

A) $\frac{2}{9}, λ$

B) $\frac{9}{2}, λ$

C) $\frac{5}{27}, λ$

D) $\frac{27}{5} λ$

Show Answer

Answer:

Correct Answer: D

Solution:

For first line in Lyman series $λ_{L_{1}} = \frac{4}{3 R}$ ….. (i) For first line in Balmer series $λ_{B_{1}} = \frac{36}{5 R}$ ….. (ii) From equation (i) and (ii) $\frac{λ_{B_{1}}}{λ_{L_{1}}} = \frac{27}{5} \Rightarrow λ_{B_{1}} = \frac{27}{5} λ_{L_{1}} \Rightarrow λ_{B_{1}} = \frac{27}{5} λ$
