The shortest wavelength of spectral line in Lyman series is 912 Å. The shortest wavelength of the spectral line of the Paschen series is

Options

A. 4143 Å
B. 4341 Å
C. 4431 Å
D. 1344 Å

Answer

B

Explanation

For `H_(gamma)` line of Balmer series `p=2` and `n=5`
`:. 1/lambda =R [1/P^(2)-1/n^(2)]`
`:. lambda =4341 Å`.
