Question

Write an expression to calculate the wave number of a spectral line in hydrogen spectrum.

Answer 1

Hi , friend !!

here is your answer !!

1 / lemda = v^– = RH [ 1/ n² - 1 / n²] × z²

1/ lemda = wave number which is reciprocal of wave length


RH = Rydberg constant = 10097.. cm-1 approx


hope it help you !!

thanks !!
