• # question_answer Which of the following spectral series in hydrogen atom give spectral line of$4860\overset{o}{\mathop{\text{A}}}\,$? A)  Brackett       B)  Paschen C)  Lyman        D)  Balmer

The spectral line of wavelength$4860\overset{o}{\mathop{\text{A}}}\,$lies in the visible region. Since Balmer series lies in the visible region of the spectrum. Therefore, Balmer series gives spectral line of$4860\overset{o}{\mathop{\text{A}}}\,$.
