The wave number of first line of Balmer series of Hydrogen is

15200\,\,c{m^{ - 1}}

. The wavenumber of the first line of

15200\,c{m^{ - 1}}

ion is

View answer and explanation

Correct option: B

60800\,c{m^{ - 1}}

Option B (

60800\,c{m^{ - 1}}

) is correct because the wavenumber is proportional to

Z^2

, where Z is the atomic number.
