Question

What is the wavelength of the spectral line associated with a transition from n=3 to n=2?

Answer 1

here is your answer!!

Lemda= { 1/ n² - 1/ n² } × R× Z²

=> { 1/ 4 - 1/9} × 9 R

=>. 5 / 36 × 9 R

=> 5 R/ 4

= > 4/ 5R

hope it helps !!

thanks !!

here R is Redburg constant value => 109700cm-1
