The wave number of first line of Balmer series of hydrogen atom is 15200 cm−1cm^{- 1}. What is the wave number of first line of Balmer series of Li3+Li^{3 +}ion.

A

15200cm−115200cm^{- 1}

B

6080 cm−1cm^{- 1}

C

76000cm−176000cm^{- 1}

D

1,36800cm−11,36800cm^{- 1}

Answer

1,36800cm−11,36800cm^{- 1}

Explanation

Solution

For Li3+ 6muvˉ=vˉLi^{3 +}\mspace{6mu}\bar{v} = \bar{v} for H×z2H \times z^{2} =15200 ×9= 1,36800cm−1cm^{- 1}
